I started this thread a few years back and I finally received a copy of the cartoon Why The Bears Dance On X-Mas Eve from a Yvette Kaplan (wonderful woman) who was the character designer at the time. I saw this cartoon in NYC in 1977 on ABC television and have posted it here and on You Tube. The company that produced it was Tele-Tactics and they no longer exist.
My last query for this cartoon is how can I find out who the voice actors were and what parts they played. There is no mention of the voice actors in the credits. I would appreciate all the help I can get. Thank you.
