Onstage I like to play with a an 18-inch speaker, which very few bass players do. I need that fat, underneath sound, which I've always had. It suits me admirably to do it like that, and I can imitate that sound by plugging directly into the board in the studio.

If you are any competent musician, if you have creative ideas, ideas of songs, of arrangements, in a band like the Stones, where these 2 people do all the things, there is no freedom.

Everything had to be done in-between Stones time.

I always listen to a lot of different music when I am working on a project.

I can't really sing and play live, because I can't play bass efficiently and sing at the same time. If I concentrated on the vocals, I'd mess up the bass, and if I concentrated on the bass, I'd forget the lines.

But why is it that in music, anything more than 5 years old - apart from a few hits - is never played on radio to the young public?

It's all right leaping about the stage when you're 20 but when you get to 25 it gets a bit embarrassing
