Wood - always the most approachable of The Stones - is an engaging character, chain-smoking and unpretentious; when you're a Rolling Stone little impresses you, perhaps, especially the vanity and huge egos of some of the subjects who sat for him. The most difficult, perhaps not surprisingly, was Jagger himself. "It's not because I know Mick so well, it's just he has so many different moods, his face changes, you know, depending on what's happening, which makes it hard to get a real, definitive portrait." Is Jagger happy with it? Wood laughs. "Let's say he's seen lots of paintings I've done of him." Another Marlboro Light (mine) is demolished. "But, yeah, it works, I think."
