U.K. - mid-sixties: I seem to remember one probationary copper who attended Ted & Ivy Poole's club in Swindon and was warned off by his senior officers along the lines of 'there will be no future in the Police if you keep going.' And then there was an electronics engineer at R.A.F. Chivenor, who always came to the local folk club, and therefore was a communist risk, and so not allowed to work on the planes without a military policemen watching him all the time - not that they had the slightest idea what he was doing, of course. There's military intelligence for you. (He now plays english concertina at Faslane!)
