When I was 15 I became a full-time singer in a band. At 18 I made my first record.

When I was 25, Abba was formed. After Abba I made three solo albums. Maybe I have been productive enough.

I spend a lot of time with the grandchildren. They love it when we sing together. It's fantastic to hear them, and they really can sing. I don't talk to them so much about 'Abba' and the past, but as they get older, they will become more aware.

The press has always written that I am a recluse and a mysterious woman, but I am more down-to-earth than they think.

I just want to live in peace and quiet.

No one who has experienced facing a screaming, boiling, hysterical audience can avoid feeling shivers in the spine. It's a thin line between celebration and menace.
