He'll probably break out all the lame hits (Freefallin, I Won't Back Down) but the Heartbreakers are still a great band, especially guitarist Mike Campbell and former Stooge Scott Thurston. If you don't have their 1999 album Echo go buy it now
post Superbowl update:
Tom Brady didn't play as well as Tom Petty
but he went down Swingin' (1999)
Tom "playing bass" with Dwight Twilley (1977)
