I've long enjoyed Tom Petty's music. Anything new on the horizon?
—Diane Koren, Hampstead, Md.
After performing the televised halftime show at February's Super Bowl, the durable rocker, 57, headed into the recording studio with the reunited members of one of his earliest bands, Mudcrutch, with whom he played back in Gainesville, Fla., in the early 1980s. Then he hit the road for a summer tour with his "full-time" group, The Heartbreakers, and their arsenal of rock hits, including "Free Fallin'," "Runnin' Down a Dream" and "I Won't Back Down." If you've been following the race to the White House, you've probably heard Petty's FM-radio classic "American Girl" used as political campaign music for Sen. Hillary Clinton. Petty is married and lives in Los Angeles.
