The Yeah Yeah Yeahs stopped by "The Late Show with David Letterman" and supported their forthcoming album "Mosquito" with a little bit of help from their friends. Backed by the Broadway Inspirational Voices, the YYYs ripped through new single "Sacrilege" on Friday night (Apr. 5).
Wearing a honey-colored, jewel-encrusted suit and blonde locks, singer Karon O led the Yeah Yeah Yeahs through the first half of the single before effectively ceding the stage to the gospel choir. The Broadway Inspirational Voices' leader, on standing on the right side of the stage, is apparently more passionate than most musicians gracing the "Letterman" stage.
