Professor Poopsnagle's Steam Zeppelin

People actually know this show. I thought my memories were kind of skewed. I still remember the theme music. Does anyone have a scratchy old video tape recording out there? Getting the theme music on the internet would be hilarious. There is so little information about this show it's ridiculous. I'm sure there are master tapes out there, rotting in a basement. I obviously saw this who on re-runs in the early 90s, I didn't know it was from the eighties. I can really only remember in detail when the professor is abducted by the bad guys and the crew have to fly the bus-air-ship by them selves and crash in the desert or something. Then the Aboriginal kid crew member does some bush-tricks to get water and goes on 'walk about'. One of the kids was a traitor or something. Also in the opening, when they're singing, you can see the inner-workings of the airship-bus, where there are spinning bicycle wheels for some reason. That was the most catchy theme music of all time... "There's a great big bus way up in the sky, and everyone said it would never never fly...." So bizarre and crazy, I just really want to see it again. Cheers
