Kevin and Bean's Christmas Album #1 : God Rest Ye Merry Gentlemen (Doc on the ROQ)

8th track (side B, song 3) from the first ever Kevin and Bean Christmas album, titled "Feel the Warmth of Kevin and Bean's Wonderful World of Christmas" (The White Album), 1990.
When the singer says at the end of the song "at least I didn't lip sync it", he was making a jab at the band "Milli Vanilli" who at the time got in trouble with their fans when it was found out that the band didn't actually sing their songs (it was discovered at a concert when the sound gave out).
