Wow! Heard this on the radio on the way home this afternoon; a genuine shock. Sadly, that's how heart attacks are: sudden and unexpected regardless of your health. Being 66 is being a senior citizen, but Petty's vitality and passion always made him seem younger (that, and his blond hair turning to gray wasn't obvious or jolting in the way going from brown or black to silver is).
Great music for over forty years. many fond memories. RIP.
Thread title changed for the obvious reason.
