Well, I can't remember if it was there in past seasons, but there definitely was one this year, during normal park operations, on my most recent MK visits on 12/31, 1/1, 1/4, and 1/6. Some of the tracks were sung by "Fab 5" characters and may have been from various WDR Christmas CDs. Other songs were sung by Pooh characters, and others were sung by non-characters.
