This is Andy Pandy. Andy was a popular puppet character in a show called 'watch with mother' - which was a silly title, as your mum could actually get on with the important things in the house while you were watching 'watch with mother' on your own. Even as a child I could see the strings holding Andy up and knew that he wasn't real. That kind of spoilt the whole show for me and put me off Thunderbirds and captain Scarlett etc.
