Scooper, Spring, Billie, Brains, Sticks, Doughnut, and Tiger, were kids who spent their time in an abandoned London bus in a scrapyard in the early 70's. There were 17 episodes, which started with this song ...
Get on board! Get on board!
Come and join the Double Deckers.
Take a ticket for a journey,
On our double decker London bus.
Ring the bell (ding ding), Toot the horn (honk honk),
When you ride with the Double Deckers.
Fun and laughter is what we're after,
On our double double double decker bus.
