SINGLE-HANDEDLY KEPT ITV in business in the early 70s, so this endlessly-mocked transportation-tweaking torpitude has got to count for something. All the critics loathed it, naturally, but fifty thousand billion viewers watched its 74,000 episodes, not to mention the (count ’em!) three film spin-offs. Roll call: REG VARNEY was the cheeky bus driver with an eye for the ladies; BOB “EDDIE” GRANT was the cheeky clippie with an eye etc; MICHAEL ROBBINS and ANNA KAREN were the comedically dire couple with a motorbike and sidecar; STEPHEN “DON’T DRINK” LEWIS was Blakey, the miserable inspector with an annoying donkey-style voice. Franchise travelled the world. Unlike the buses.
