If you went to see Legally Blonde: The Musical like what I did last year, Peter Davison would have been amongst the cast. In the programme, among his various credits (you know, like Doctor Who, All Creatures Great and Small, et al), he says that the thing he's most proud of is that he wrote and sung the theme song to Button Moon.
I'm guessing he left out The Tomorrow People for a reason.
Anyway, Button Moon, as the theme song suggested, sees Mr. Spoon travel to Button Moon in his homemade rocket-ship (all of the characters in the show are based on kitchen utensils, as well as many of the props). Once on Button Moon, which hangs in "blanket sky", they have an adventure, and look through Mr. Spoon's telescope at someone else such as the Hare and the Tortoise, before heading back to their home on 'Junk Planet'. Episodes also include Mr. Spoon's wife, Mrs. Spoon, their daughter, Tina Tea-Spoon and her friend Eggbert.
Amazingly, the series lasted for 91, 10-minute episodes. And Peter Davison (with Sandra Dickinson, his then-wife) sung the theme tune to all of them.
