On Monday, news spread that rock ‘n’ roll icon Tom Petty was found unconscious and in full cardiac arrest at his Malibu home Sunday night. Some reports have said that the Rock and Roll Hall of Famer has died at age 66, although the Los Angeles Police Department has not confirmed the singer’s death.

TMZ now reports that Petty is “clinging to life,” but is not expected to live through the day.

What’s clearer is that Tom Petty’s music touched millions, including one of Seattle’s most famous rock stars.

Petty and Eddie Vedder hooked up several times over the years and each time it was as dynamic a performance as you’d expect from the two rock legends. In 2012, Vedder joined Petty on stage at the Heineken Music Hall when their respective tours crossed paths in Amsterdam. Vedder made a surprise appearance to trade verses of “The Waiting” with Petty before rejoining him during the finale of “American Girl.”

It wasn’t the first time the music greats connected, as Vedder had previously lent his vocals to “The Waiting” during a 2006 gig in Denver. That same year, Vedder busted out a tender acoustic version of Petty’s “I Won’t Back Down”—a tune he’s often covered—during a Pearl Jam show at the Gorge. Watch each performance below.
