But really, how long? "Well, a few years now." Do they live together? "Ooh, no. No. I'd very quickly tire of anyone actually living with me." They met on Ibiza, where Ian, who's 30, was working and Clary was on holiday. What's he like, then? "He's very clean-living. He wears a halo. He doesn't drink, smoke, take drugs. He barely breathes." And all of a sudden, Clary is starting to sound like Kenneth Williams. The idea of marriage intrigues him, you sense, but he claims that the "heaviness" of it - as a contract between two people and as a symbol of gay civil rights - makes him uncomfortable. "I don't think we'll get married because I'm much richer [than Ian] and if it went wrong he'd want all my money," he says smoothly. "Actually, I think I lead my life too flippantly to engage in anything like that ... You've really got to be sure it's what you want. And I don't want it." He laughs suddenly, embarrassed by his own vehemence. He would have loved children, though, and oddly - despite the self-confessed frivolity of his London lifestyle - would have made a good family man, you feel. "When I was about 40, I did suddenly think, oh dear, I'm not going to have children. And I looked into all sorts of possibilities, including adoption and lesbian friends with turkey basters. I got quite close actually, with a friend who was on tour with me in Australia. We'd worked everything out ..." He stops, aware that he's ventured onto too-serious territory - and swerves back to the safer joke. "But it would have meant masturbating in Brisbane, so that was out of the question."
