Mr Piper was a TV show hosted by a large Canadian opera singer chap, wearing pied piper stylee get up. He would sing and narrate stories that would be shown as cartoons, which you always went out the window at the back of the house to see.
Then there was 'Down on Animal Farm' another narrated story, this time he would point down to a hole in the skirting board and there would be real little animals (mouse, hamster and a rat?).
He also did magic tricks that he produced out of his big bag and there was the talking parrot too!
