And there are certain songs that are really timepieces and shouldn't be touched. But some of them are a celebration of good humour and sensibility and I think that's okay. I don't care about the past, I'm a musician with ambition.

Come into my life, here where nothing matters. Come into my life, roll away the gloom.

I want to play tennis and fornicate.

When I was a kid, the world was such a big place, and I had no idea that I would be afforded these great moments in between doing what I love to do.

I'd break out in hives if I had to sing (`Stairway to Heaven') in every show. I wrote those lyrics and found that song to be of some importance and consequence in 1971, but 17 years later, I don't know. It's just not for me. I sang it at the Atlantic Records show because I'm an old softie and it was my way of saying thank you to Atlantic because I've been with them for 20 years. But no more of `Stairway to Heaven' for me.

If you do what you think is right for the benefit of everybody and everything and you make decisions, to go back and regret them afterwards - it's a futile experience and it's not worth thinking about. Because life just unfolds. Provided you do your best and you think you're on the right track, you can only be right or wrong. But to regret it - I don't think there are any huge errors or misdemeanors.

There's no point stepping up to the golden platform if you're going to repeat yourself.
