I'm about 90% sure I still have a VHS tape with this special on it dating back to the original airing.
The thing I remember best about this special was a sneak preview of GARFIELD AND FRIENDS with Jon singing "Eat, Garfield, Eat". Also, there was a bit where two composers, I want to say one of them was Desiree Goyette (also the voice of Arlene), composing a song called something like "We've Got It All and That Ain't Bad" in only around two hours. They said it was going to be used for the GARFIELD: HIS NINE LIVES special, but I don't think it ended up being used for anything (other than demonstrating the process of quickly composing a song in this special).
