I have this vague, nagging memory of a thread about the music CDs from some years ago in which a very knowledgeable fan either stated outright, or speculated, [spoiler]that the "bongo freakout" cue was originally recorded for the 1970 Destruction of Collinwood sequence.[/spoiler]
I believe the discussion concerned cues that still had yet to see release on CD, or any other format for that matter.
Golly, some of those holiday smilies are frightening!
