Pearl Jam singer Eddie Vedder made a surprise appearance at the Oscars Sunday night, covering Tom Petty’s “Room at the Top” during the show’s “In Memoriam” segment.

Eagle-eyed Twitter users saw the singer at the beginning of the broadcast, seated a few rows behind Meryl Streep. Armed only with a solitary electric guitar, Vedder’s bittersweet cover of late-era Petty (the song is from 1999’s “Echo), who also died in 2017, and was backed by a string section as images and clips from the likes of John Heard, Jane Foray, Martin Landau, Glenne Headly, Roger Moore, George A. Romero and Jerry Lewis flashed on the screen.

Vedder was introduced by Jennifer Garner. “There is no joy without sorrow,” the actress said as she noted the achievements from those who featured in the video.
