Led Zeppelin pair joins Foo Fighters onstage

Jimmy Page, John Paul Jones at Wembley show

NEW YORK -- Led Zeppelin guitarist Jimmy Page and bassist John Paul Jones turned an already high-profile Foo Fighters show into a once-in-a-lifetime event Saturday night at London's Wembley Stadium, joining the Foos for covers of Zeppelin's "Rock and Roll" and "Ramble On."

Drummer Taylor Hawkins took the microphone for the former, while frontman Dave Grohl sang the latter. Grohl, a lifelong Zeppelin fanatic who was on hand for the group's one-off reunion in December in London, told the crowd Saturday's experience constituted "the greatest day of my entire life."

The Foos' summer European tour continues Wednesday in Bergen, Norway, and wraps June 22 at Germany's Southside Festival. A North American run begins July 9 at Seattle's Key Arena.
