Tom Petty, legendary rock star and frontman for Tom Petty and the Heartbreakers, has died at 66 years old. He was found unresponsive and in cardiac arrest on Sunday night. TMZ reports that he was transported to UCLA Medical Center, but showed no signs of brain activity, and was removed from life support today.

UPDATE: According to TMZ, the singer has a do not resuscitate order in place and while his life support has been removed, he is still clinging to life as of 4:35pm EST. They write, “Sources tell us at 10:30 Monday morning a chaplain was called to Tom’s hospital room. We’re told the family has a do not resuscitate order on Tom. The singer is not expected to live throughout the day, but he’s still clinging to life. A report that the LAPD confirmed the singer’s death is inaccurate — the L.A. County Sheriff’s Dept. handled the emergency.”

Tom Petty and the Heartbreakers rose to fame in the 1970’s. It’s hard to imagine classic rock without mentally running through his catalog. “American Girl”, “Free Fallin'”, “Breakdown”, and so many more. Tom also enjoyed commercial success as a solo artist.

Tom Petty and the Heartbreakers were inducted into the Rock and Roll Hall of Fame in 2002.

As news of his passing spreads, people are taking to social media to share their love of one of the fathers of classic rock and roll.

It’s hard to put into words just how many people Tom’s music touched.

The band had just concluded their 40th anniversary tour. Last Monday, they played three sold-out shows at the Hollywood Bowl. Last December, Petty told Rolling Stone that this tour would likely be their last.

“We’re all on the backside of our sixties. I have a granddaughter now I’d like to see as much as I can. I don’t want to spend my life on the road. This tour will take me away for four months. With a little kid, that’s a lot of time.”

In his downtime, Tom kept himself busy with his own SiriusXM channel, “Tom Petty Radio”. We’ll be listening to it all day, that’s for sure. Rest in peace, Tom. Thank you for the music and the memories.

“All the good girls are home with broken hearts”. Yes, we are. Goodbye to another legend.
