About three hours ago, American Idol cutie patootie Kris Allen tweeted that he would be performing with a “special guest” on tonight’s episode of The Late Show with David Letterman. As you see here, said special guest was going to be Santa Claus playing the drums, but apparently the folks at The Late Show are in cahoots with the Grinch and nixed Kris Kringle pulling off his best Ringo. EW is waiting for clarification from the show’s producers, so if we do hear why Letterman and co. have declared war on Christmas cheer, you all will be the first to know.

UPDATE: CBS tells us “the whole band ended up wearing holiday sweaters for their appearance.” The holiday spirit lives!
