I bought a Mercedes convertible brand new in 2016 and I’ve only done 4,000 miles. I love cars – if I’m going to blow it, it’ll be on a sports car. I already have my eyes on the next one – I’ll get Simon Cowell to buy it.

A guitar – a 1959 Gibson 335.

Probably a suit. If you buy a good suit, it lasts beyond your lifetime.

My partner was doing a play in Hong Kong last year and I went to visit him, and I bought him a beautiful teacup. But I didn’t look at the price tag before I took it to the till and it was £100, the most expensive teacup imaginable.

When something is half price in a supermarket, always find out why.

I can go for weeks without opening the mail. I can look at a letter that has just dropped through the letterbox, wonder what it is and then just shred it.

Audiobooks have allowed me to catch up on the books I always claimed to have read anyway. On long journeys I’ll often be listening to Kafka, Dostoevsky, Solzhenitsyn. It’s a fantastic way to pass time and often means I’ll turn up at the gig really depressed. So it’s a win-win.

After the third time someone’s late, we can’t be friends any more.
