Willie Nelson in A Colbert Christmas sings of peace on earth. The graphics are excellent, as is his command of the lyrics:

What, no mention of biowillie (biodiesel)?

Feist’s rendition of “Please Be Patient…Due to Increased Prayer Amounts” is aslo amusing, especially the part where she explains that prayers will be taken in the order that they were received. Sadly, she does not reach the lyrical achievement of Nelson, but I think that is because of the format she was given. I wish (not pray, mind you) that Feist had been allowed more of her usual punchy rhythmic upbeat style instead of a syrupy formulaic hymnal, but I suspect Colbert was going for a different style of parody.
