Jimmy Iovine tells an excellent story about the pairing of Tom Petty and Stevie Nicks in Peter Bogdanovich's great film about Tom Petty & The Heartbreakers, Running Down a Dream. Iovine loved having Nicks sing lead on "Stop Dragging My Heart Around" because he loved hearing a woman sing the role normally sung by a man.
