[quote:2jo1ejjr]Foo Fighters' Dave Grohl and Pat Smear joined Pearl Jam's Eddie Vedder onstage in Seattle for an impromptu collaboration earlier this week (April 27).

The trio appeared during the encore at Mike Watt & The Missingmen's gig at the city's Triple Door venue - scroll down and click below for fan footage of the hook up.

During a ten-minute session, the grunge veterans performed a version of Watt's 1995 track 'Big Train', with Grohl playing drums, Smear on guitar and Vedder adding guitar and vocals.[/quote:2jo1ejjr]
