Singer Stevie Nicks has stunned Fleetwood Mac fans by revealing she would have quit the supergroup at the height of its success if Tom Petty had asked her to join his band THE HEARTBREAKERS. Nicks, who duetted with Petty on 1981 hit Stop Draggin' My Heart Around, was such a fan of the rocker she'd have quit Fleetwood MAC, then basking in the success of one of the most successful albums of all time, Rumors. She says, "In 1978, if Tom Petty had said, 'Leave Fleetwood MAC and come and join us,' I would probably have joined Tom Petty + The Heartbreakers."
