Flaming Lips & Sean Lennon perform "Lucy in the Sky with Diamonds"

Flaming Lips Lucy in the Sky

Perhaps taking a tip from Jimmy Fallon's Pearl Jam week, David Letterman's hosting a bevy of Beatles cover performances this week to celebrate the 50th anniversary of the Beatles' first appearance on the Ed Sullivan show on February 9, 1964. The Flaming Lips performed last night and brought with them possibly the most obvious Beatles song the Flaming Lips could possibly cover, "Lucy in the Sky with Diamonds," but they also brought along Sean Lennon, a metric ton of confetti, and some tinsel wings for Wayne Coyne. Check it out.
