IMAGINE the conversation. "We want people to drop less litter so why don't we have four comely young women dancing awkwardly on a platform in the street while wearing very short shorts and white boots. That should work."

This, as the t-shirts suggest, is the Keep Britain Tidy campaign, with Keep Scotland Tidy as a poster afterthought, in Glasgow's Buchanan Street in September, 1973. Even the Evening Times was unsure of the connection as it tentatively stated: "They danced to the latest record to put over a strong anti-pollution message." The photographer described them as "go-go dancers" on the back of the photograph, which is a phrase you don't hear that often. Lady on the left is Michelle Lane who became a Tennent's Lager Girl and a footballer's wife which seemed to be a regular career path back then.

Surprisingly the Keep Britain Tidy campaign still exists, suggesting that once folk create comfy jobs, they don't easily give them up.
