Rock chick Suzi Quatro still feels guilty for ditching her bandmate sisters to pursue solo success when she was 21. Quatro jumped at the chance to become a star and moved to London in the 1970s, leaving her group Cradle and her siblings behind - and it still haunts her. The 57-year-old says, "When I was 21 I decided to move to London to try for a solo career. I was in a band with my sisters and my father said, 'You know, you're sisters aren't going to make it without you,' and I said, 'I've got to go', "I had that hanging over me and I still do."
