OK, you got my curiosity going, so - the series was German, made in 1958, shown on Breitish TV in 1958 in black and white, and again in the 1970's in colour. To save money, the UK producers simply turned down the German dialogue, and voiced a naration over the top. the story concerned a preincess, wooed by a prince. She rejected his gift of jewels, and demanded a singing ringing tree. The prince found it in the land ruled by a spiteful dward, who turned him into a bear, and captured the princess, removing all her beauty. As the two sad characters slowly fell in love, the dwarf's power was diminished, and it all ended happily ever after. It's based on a Brothers Grimm story 'Snow White and Rose Red' and it's been a cult classic ever since its initial showing - you can get it on DVD if you want to stir those old memories again.
