The Foo Fighters were joined onstage by Led Zeppelin's guitarist Jimmy Page and bassist John Paul Jones Saturday night as they wrapped up a two night stand at London 's Wembley Stadium. The audience was treated to a pair of Zeppelin classics -- 'Rock and Roll' and 'Ramble On' -- during the encore.

"Tonight playing here at Wembley Stadium is an honor and if we didn't take advantage of this opportunity we'd be crazy," frontman Dave Grohl told the crowd. "We knew from the beginning this wasn't going to be another outdoor show, we have been planning this for six months so we would like to welcome Jimmy Page and John Paul Jones onstage."

The Foo Fighters brainchild and former Nirvana drummer took over the sticks while drummer Taylor Hawkins sang vocals on 'Rock And Roll.' Grohl returned to the mic for a rousing version of 'Ramble On,' telling the crowd, "Welcome to the greatest day of my whole entire life."

Page and Jones last performed publicly in December 2007 with singer Robert Plant at Led Zeppelin's London 02 Arena concert. Reports of a possible Toronto gig this summer, which leaked last month, have subsequently been squashed.
