When I was kid back in the 60's, The Three Stooges were rescued from obscurity by a guy named Paul Shannon who had a kid's show called "Adventure Time" on WTAE TV out of Pittsburgh. He even had them as guests on the show. Most sources credit him w/ restarting their career. As a bit of trivia, jazz guitarist Joe Negri (Handyman Negri from Mister Rogers)also had a kid's show that aired right before Adventure Time every afternoon. BOth shows were done live.
Don't confuse the color Frosty 1/2 hour cartoon (Jimmy Durante narrates) with the b&w short I mentioned. It has no story line other than the one from the lyrics of the song and the song is sung a capella. The animation style is very spare and Frosty is more than a little creepy. Hardrock, CoCo, and Joe (are they in Lord of the Rings?) is done in stop-action animation, as is Suzy Snowflake.
