But when I started writing songs, I stopped painting completely, and the only art things I do are connected to the career, like album sleeves and, to some extent, posters and things like that.
I like lots of songs, and I find it quite interesting to do [cover songs] from time to time. My first solo hit was in 1973, the [Bob] Dylan song "A Hard Rain's Gonna Fall."
It's good having a lot of different songs to choose from to do the show. It means you don't get bored of doing it in one particular genre.
You become acutely aware, if you're touring a lot, that you need new songs to invigorate the live show. And make it interesting for yourself, too.
I did some songs for Baz Luhrmann's The Great Gatsby. I had done a jazz album of Roxy songs, and they used bits of it in the film. It would be nice to score a movie one day.
