My greatest experiences in the theatre and the most religious experiences in my life - of which going to the opera is one for me - have been with the Romantic composers' repertoire: it's Wagner, it's Strauss, Verdi, Puccini. That era gets me every time.

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 make the mundane fabulous whenever I can.

Musically I'm able to keep going, because it's not about money and it's not about success. It's a challenge.

I was keenly aware that I didn't want to draw on too many typically doomed aspects of the fated singer. Whether it's Judy Garland or Norma Desmond, there is this tragic quality to older women that one can revel in, and you want it to be more three-dimensional than that. So it was important for the character to be strong and resilient, because there are so many victims in opera.

I love being not cool.

Why be in music, why write songs, if you can't use them to explore life or an idealized vision of life?
