At 37 Crawford Road in Camberwell, London. My mother had separated from my father and we had nothing, but I remember roast potatoes, twopence in the gas meter and music. It was the only time in my life when I felt at home.

Lots of times, mostly all connected to Gordon and my children.

The 60s at the University of California at Santa Barbara weren’t bad.

When our family was complete.

It’s a calm and secure feeling of deep loyalty.

Bill Gates. Not only did he build Microsoft, he went on with his wife to create the Bill & Melinda Gates Foundation. They support the, in my view, single most important factor in making the world a better place – empowerment of women and girls.

My surname. You have no idea how many versions I’ve read and heard. It was especially irritating during my Abba years. You can imagine someone calling our hotel and saying: “I’d like to speak to one of the guys in Abba.” Who do you think the receptionist called, Andersson or Ulvaeus?

In my professional life, the musical Chess on Broadway. It was a resounding fiasco and played for two months. The butcher of Broadway, Frank Rich of the New York Times, was probably very pleased: I’ve never seen such a bad review in my life.

A cabaret act with Agnetha, Frida and Benny. It was in a nightclub in Gothenburg and one night we had seven in the audience. It was before we found out that we were a pop group.

Nothing, really. But without little sleeping pills, I’d go crazy.
