"What's inside the singiiii-nnnng... KETTLE
The Singing Kettle was a strange Scottish kids tv show/live show where the presenters would sing such songs as "Little Bunny Foo Foo" and "Mr Pizza Face" at/with the audience. They used to go on tour and at one point kids were flocking for tickets to sit as the live audience.
I'm not sure whether or not it's still about but you sure can still buy the video.
