I seem to recall that there was a Famous Classic Tales adaptation of A Christmas Carol. I vaguely remember the Williams/Jones version, if at all. I've only seen pieces of Mickey's Christmas Carol, but not the whole thing.
Mr. Magoo's Christmas Carol, IIRC, came out in 1963 or '64, not '62. I've seen it a few times, moreso than the others on the list. Speaking of lists, here's mine:
Mr. Magoo's Christmas Carol. I've always thought it came out in '64, same as the Famous Adventures series. Very entertaining.
Stingiest Man in Town. A Rankin-Bass production often forgotten, with Walter Matthau & Tom Bosley. Seen it only once.
A Flintstone Christmas Carol. IIRC, Fred's juggling playing Scrooge and trying to find some last minute gifts. Didn't think it was that late in coming out ('94). Thought it was sooner than that.
Beavis & Butt-Head "Do Christmas". One of the few B & B eps I actually liked, as they not only parodied Carol, but also "It's a Wonderful Life".
