Lenny Kravitz Does ‘Get Back’ On Letterman [VIDEO]

David Letterman does his show in the very theater where America met the Beatles 50 years ago. Very cool that he is celebrating the anniversary with Beatles Week! Last night Lenny Kravitz did a faithful, ripping version of "Get Back" featuring Paul Shaffer tickling the electric piano ivories. We can't wait for the Beatles Special! It's this Sunday night on CBS.
