To those of you who are wearing ties, I think my dad would appreciate it if you took them off.

My training as an engineer has enabled me to design the stuff, but the reason I do it is not to make music but for the opportunity to work with musicians.

I was never worried that synthesizers would replace musicians. First of all, you have to be a musician in order to make music with a synthesizer.

When a pianist sits down and does a virtuoso performance he is in a technical sense transmitting more information to a machine than any other human activity involving machinery allows.

I'm an engineer. I see myself as a toolmaker and the musicians are my customers... They use my tools.

I happen to think that computers are the most important thing to happen to musicians since the invention of cat-gut which was a long time ago.

What inspires me is not so much the music as the opportunity to interact with composers. I think that has driven everything I've done.

One always has to remember these days where the garbage pail is, because it's so easy to make sounds, and to put sounds together into something that appears to be music, but it's just as hard as it always was to make good music.

Back in the '40s and early '50s, building simple electronic projects was a popular hobby of many people. Back then, you could buy, you know, a few parts and - with tubes and build something on your kitchen table, and it would actually work.

By the time I got to building synthesizers, I had perhaps 20 years' experience building electronic musical instruments.

Everything has some consciousness, and we tap into that. It is about energy at its most basic level.

I had been building electronic musical instruments since I was a kid.

I'm finishing building a house and setting up a shop to build custom electronical musical instruments.

Leon Theremin's original designs are elegant, ingenious and effective. As electronics goes, the theremin is very simple. But there are so many subtleties hidden in the details of the design. It's like a great sonnet, or a painting, or a speech, that is perfectly done on more than one level.

My transition from scientist to entrepreneur? Some would say that I still haven't made that transition.

Other kids went out and beat each other up or played baseball, and I built electronics.

The mini-Moog was conceived originally as a session musician's axe, something a guy could carry to the studio, do a gig and walk out.

The point is that I don't design stuff for myself. I'm a toolmaker. I design things that other people want to use.

There are confirmed stories of people who can break instruments and cause them to fail by walking in a room. I'm the opposite - I can walk into a room and something will work better than it is supposed to.

When we started making electronic music I imagined that the reaction we got from the rock musicians must have been similar to the one the beat groups got from people like my dad.

It was tough at the time but when I was younger, my Dad. I would say my Dad, because without him I wouldn't have been here. I mean it was tough for me because he was really demanding. With him, it was never enough, you know, anything I did was never enough.

David and Dad didn't get along too well growing up. I mean we all got along, but it was harder on David, because David wasn't going to be the son that Dad wanted. But now they're like best friends.

Where I come from, you don't really talk about how much you're earning. Those things are private. My dad never told my mum how much he was earning. I'm certainly not going to tell the world. I'm doing well.

I feel lazy when I'm not working. I learned all my business sense from my dad. He always believed in me, and I think the last thing he said to me before he passed away was, 'I know you're gonna be OK. I'm not worried about you'.

And I love Mel Brooks. My Dad loved his movies, too, they're awesome, the kind of thing that if you're in for ten minutes, you're in for two hours.

My mom and dad met at UCLA when he as a captain in the Air Force and she was in her junior year.

My dad was born in Chicago in 1908... his parents came from Russia. They settled in Chicago, where they lived in a little tiny grocery store with eight or nine children - in the backroom all together - and my grandmother got the idea to go into the movie business.

Mom and Dad would stay in bed on Sunday morning, but the kids would have to go to church.

My dad was dean of fine arts at the university. I was casting bronzes in the school foundry. I was using the university as a playground.

I have to remind my dad, 'Journalists - no matter how many cigars they smoke with you - are not your friends, so don't talk to them.'

We came from a family where we ran our own small business. Our dad made his own products. We made our own sausages, our own meatloafs, our own pickles. Dad had to do everything himself. He had to figure out how to finance his business.

My dad was a carpenter and I would work with him during the summer and umpire on the nights I wasn't playing.

It was sort of just a family sport. My mom and dad were pretty keen golfers when I was young and so were my grandparents, and I just sort of tagged along with them.

My dad takes care of me as a manager and as a dad. That's his job, you know, to take care of me. He has my best interests at heart.

My mom and dad are both in stand-up comedy, so that's where I started, that's where I got everything. My roots are holding the mic.

Joanna points her camera at a section of society unused to having cameras pointed at it. But I don't know about categorizing them in terms of class; I'm a bit wary of that. My dad is the son of a shipbuilder.

Now my dad is with me, traveling with me and a big part of this whole thing is I like to mix it up a little bit, you know. Who gets to take their father on a private jet across the country and stay in first class hotels? So we're enjoying it, but I'd stop if it's not possible.

It was my 16th birthday - my mom and dad gave me my Goya classical guitar that day. I sat down, wrote this song, and I just knew that that was the only thing I could ever really do - write songs and sing them to people.

Jenna's traveled with me; they've both traveled with their dad. This is the only time they've been old enough in all of their dad's campaigns to really be involved in.

I was a very sickly kid. While I was in the hospital at age 7, my Dad brought me a stack of comic books to keep me occupied. I was hooked.

My dad has no control over who works with me. Me, me and me alone has to take responsibility for anything.

My dad says I could sing before I could talk, if that's possible. I was always humming and things like that.

No, like I said, my dad was never really part of the tennis. His involvement around what I did with the tennis and with my mom and my grandparents was really not a part of my life.

I didn't know my dad for a long time. My dad was on drugs and my dad was at the VA Hospital, my dad was off in his own world selling drugs or using them or there would be crack heads in the house or whatever it would be.

I'm in the Rock and Roll Hall of Fame on the One-Hit Wonder Wall. I'm still very troubled by the fact that I'm in the hall and my dad isn't.

Dad bought me a toy drum one Christmas, and I eventually destroyed it. I wanted a real drum and he bought me a snare drum. Dad continued to buy me one drum after the other.

But although Australia was also involved in the Vietnam conflict, I can remember my dad telling us that if we were in Australia, we wouldn't be drafted until we were 20.

My dad always used to tell me that if they challenge you to an after-school fight, tell them you won't wait-you can kick their ass right now.
