VIDEO: Eddie Vedder Singing at The Oscars For In Memoriam

Eddie Vedder was the surprise voice of this year's Oscars In Memoriam tribute and he honored one of his own by performing a Tom Petty song.

The Pearl Jam frontman sang "Room at the Top," the lead-off track on Petty and the Heartbreakers' 1999 album, Echo. He played the song on a Rickenbacker guitar accompanied by strings and longtime Pearl Jam producer Brendan O'Brien on keyboard and backing vocals. You can find video of the nearly four-minute segment on YouTube.
