"...plum in mouth.."    Different strokes...    I like a lot of Kings Singers renditions. Though admittedly "Here Comes Santa Claus" or "Jingle Bells" would not be the best choices for repertoire for them--if they've ever recorded these. (Though a self-parody rendition of these could be a hit.) I'd far rather hear their version of "I'll Be Home For Christmas" however--which they could do well, I'm sure-- based on reports of Dylan's performance.   Dylan would fit well on a CD also including the Chipmunks.   The Chipmunks however have both humor and charm.

As others have suggested, it sounds like the best approach is just to give to charity what you might have been tempted to spend on this album.
