You've got to believe in yourself, or no one will believe in you. Imagination is like a bird on the wing, flying free for you to use.

I'm into rock'n'roll because rock'n'roll, to me, means freedom.

In those days, if you wanted a new car or a holiday, you'd phone up the office and they'd send you some cash. You never had a bank account. I don't know anyone from the music business in the Seventies that it didn't happen to.

But the thing with us was, we didn’t really need anyone to make us world famous – we were already halfway there.

I wish I didn't have to perform 'Iron Man' every night.

I listen to some of the lyrics I used to write and I say, "Where was my head at when I wrote that?"

There are no impossible dreams.
