Urban, Paisley perform for Beatles Special

Keith Urban performed with John Mayer during Sunday's CBS Beatles special, which celebrated the 50th anniversary of the band's appearance on the Ed Sullivan Show.

 The duo performed "Don't Let Me Down."

"I had seen them do 'Don't Let Me Down' at the Eric Clapton Crossroads show last fall at the Garden in new York," TV show producer Ken Ehrlich said, "and it was really amazing, with some blazing guitar solos. So I thought that would be great."

Also performing on the night was Bra Paisley and Pharrell Williams singing "Here comes the Sun."
