Where can I find a copy of an old television special based on The Twelve Dancing Princesses?

When I was little a friend of mine had taped an old television special based on the Twelve Dancing Princesses, and I would like to find a copy. I'm not sure if it was in black and white or if the television we watched it on was just black and white. Going from my unreliable childhood memory, in the show the witch gives the hero a few gifts to help him on his journey, among them an invisibility cloak, and at the end he is given the choice of the twelve princesses to marry, and he chooses the eldest, though she thought she would never marry. Does anyone know what I'm talking about, who played in it, and where I could find a copy if it exists?
