Flaming Lips

The Flaming Lips may be pranking the rock world by announcing an "immersive companion piece" to Pink Floyd's classic.

All week long, CBS' 'The Late Show with David Letterman' has been celebrating the 50th anniversary of the Beatles' arrival in America with other musicians performing their songs. Last night, it was the Flaming Lips' turn, and they brought along a friend with a personal connection to the band, John Lennon's son, Sean Ono Lennon, on 'Lucy in the Sky with Diamonds.'
