For some time now, I have been plagued by vague memories of a kids' TV show with an English double-decker bus, and a clubhouse with a secret entrance, through a fence opening. I could never remember the title, since I saw it when I was very young. Then, lo, I found the answer in a book about the Harlem Globetrotters (of all places). I knew I wasn't imagining things! The book talks about the Globertrotter cartoon, at one point, and mentions the competition, including a show called "Here Come the Double Deckers." That really sounded familiar. After a quick jaunt here and to the fan website, I have confirmed my memories. The show existed! I was only 3 or 4 when the show appeared on US TV, which is part of the reason I had a hard time remembering. I vaguely remembered the bus and the secret fence entrance, although I thought they might be two different shows. I really don't remember the episodes, but I do remember that I never missed the show, if I could help it. It seemed very imaginative and entertaining. The only other live shows of that era, that I can still recall, are The Monkees, HR Puffenstuff, and Lancelot Link, Secret Chimp. The American shows had the advantages of repeats, which is why I remember them with more clarity.
I would love to see this again, to see if any more neurons are shaken loose. It had to have been good to leave that much of an impression; nagging images from 35 years ago.
