I have this on video, I think I got it for my 4th or 5th birthday. It's called "Sooty and Superdog" or something like that. It has the dance episode, the water episode (which has the Dirty Jack song) and Superdog, where Sweep dreams he is a superhero. I can't remember the lyrics, but if I watch the video I'll come back and let you know! Not sure how good the video is now, though, I watched it to death when I was little.

Of all the friends I've had... you're the first.
Thank God the whole thing wasn't some manifestation of my darkest fears, played out as a faux Childhood memory. I think the video I had also had a special appearance from Duncan Goodhew, the swimmer. He fascinated me as a kid as he lost his hair when he fell out of a tree. I always assumed that he fell out of it, and when he picked himself up all his hair was on the floor.
