That’s the one I was thinking of!
That one used to have backing vocals to the tune of jingle Bells:
“Floating Heads, Floating Heads”
Even as a child, my mind conjured up a vision of decapitated heads floating down a river!
Awful, I know...but I remember it distinctly! LOLOLOLOL!
My first thought as well.
You beat me to it. Moreover Santa rocks :)!
