I've been thinking of trying my hand at rap. I've been recording snippets on my BlackBerry.

My parents were serious working musicians, but they were not stars - not like pop stars that you have now. They had to make a living and that meant touring, working hard, going on the road - and we were roped in.

I am ridiculously high-maintenance.

Arguably, the relationship between Liza Minnelli and Judy Garland is one of the great mother-daughter sagas of all time. Certainly, for certain people, and a lot of them, Liza is the bigger star. Liza is the more kind of viable legend, shall we say. Then there's the other camp, where Judy is the one.

I definitely have a Luddite's approach to what's going on. I find that as I get older, I get stupider. For me, the iPhone is harder than reading Faust. I've been hanging out a bit with Lou Reed, and he's the complete opposite. He's into technology and is kind of like a toddler, compared to me, who's like an old 19th-century widow or something.

I like to sing to Verdi, I like singing to Sibelius, and Mahler maybe.

Well, my great lesson with that was I went to the same production twice - once completely high and once completely sober - and both times were equally wonderful.
