Getting to No. 1 makes everyone feel better; of course it does. But it's swings and roundabouts with these things. Sometimes you make a great record, and it clicks with people. And other times it passes them by; there's nothing you can do. It's still the same record.

I'm sure there's a subconscious 'go for it' thing with turning 50. You want to do as much as possible and there are thoughts of how little time we have on the planet. For a lot of musicians in their 50s, the best days are behind them. I'd like to try and show that there is a future.

Of course I'm proud of what I've done, but I'm interested in what's next. I want to be relevant now, in 2012. I've done my bit for the past. I've only ever been about what's next, really, and I'll be that way until I keel over.

I take my hat off to people like the Stones, but it's not for me. I couldn't do that. Jagger is brilliant and long may he rock. I couldn't make my career out of old songs; it would do my head in.
