Stumbled on this listing in the TCM schedule for Tuesday, March 18:
Ice Aces (1948)
This short film provides a behind-the-scenes look of the Ice Capades practices with ice skating favorites.
Dir: David Barclay
Here's the IMDb page for the film: http://www.imdb.com/title/tt0343819/
I've seen fillers like this start a bit earlier or later than indicated in the schedule. For anyone interested, I'd suggest recording at least 12:15 PM - 12:35 PM.
