Paul Simon Finally Performs with Member of Grateful Dead

It took 52 years, but Paul Simon finally got his chance to perform with a member of the Grateful Dead.

Onstage at the Outside Lands festival in San Francisco's Golden Gate Park Sunday, Simon recalled that he went to invite the Dead to join him and Art Garfunkel at the nearby Monterey Pop festival in 1967. He said, "I knocked on the door of the house and Bob Weir opened the door. We've been friends ever since, but actually this is our first duet."

Weir then joined Simon for "The Boxer."

Simon, who no longer tours, donated the profits from his performance to the San Francisco Parks Alliance and Friends of the Urban Forest.
