When it comes to weirdness, you can't beat kids show Get Up and Go! and its follow-up show Mooncat and Co. The premise was simple: a talking cat from the moon comes down to Earth and moves in with the shows' host, Stephen Boxer. Together with a variety of other people - Beryl Reid in Get Up and Go! but Pat Coombs, Kenny Lynch, Wilf Lunn and others in Mooncat and Co - Boxer would educate Mooncat in human ways.
Get Up and Go! ran for three series before Reid was offered a job in a major ITV drama series, so her character moved out and the show became Mooncat and Co, which ran for another two series.
And here are its weird old titles.
