You see, my mother was a district nurse until she died when I was 14, and we used to move from time to time because of her work.

The last time I twerked I was with @katyperry. She was rather good at it!

I did cocaine for about a year around the time of Sgt Pepper. Coke and maybe some grass to balance it out. I was never completely crazy with cocaine. I'd been introduced to it and at first it seemed OK, like anything that's new and stimulating. When you start working your way through it, you start thinking: 'Mmm, this is not so cool an idea,' especially when you start getting those terrible comedowns.

I tried heroin just the once. Even then, I didn't realize I'd taken it. I was just handed something, smoked it, then found out what it was. It didn't do anything for me, which was lucky because I wouldn't have fancied heading down that road.

My message is a peaceful one and I hope that the idea will spread.

Going to do it to you sweet banana, like it's never been done, and we'll get high, high, high, in the mid-day sun.

There's nothing bigger than being asked to perform at the Super Bowl.
