Super-Duo: Neil Young & Paul McCartney

London's Hyde Park rates considerably more than passing mention in classic rock history. In 1964, the cover of the Beatles For Sale album was shot there. In 1969, it was the scene of the first live concert performance by the short-lived super-group Blind Faith. It was the venue for London's Live 8 performances in 2005.

Last weekend (6/27) classic rock fans were treated to yet another Hyde Park happening. There was Neil Young, on stage performing one of the scheduled gigs on his current European tour. Suddenly, seemingly out of nowhere, Paul McCartney appears on the stage for a surprise Young-McCartney duet on "A Day In The Life."

Pretty heady stuff. A fan's camera was rolling, so you can see it for yourself.
