"The Manger Zone," RPM (YouTube)

OK, everybody is getting excited because "Bumlaser," some guy on Twitter, expressed disappointment that when he discovered Kenny Loggins had made a Christmas album, it was called December and not Highway to the Manger Zone. And that this tweet reached Kenny Loggins himself, who then improvised a version of it in a Facebook video. Turns out musical parodists RPM had already covered this ground years ago. They're notoriously difficult to search online, so this amateur video is the best I could do.
