The guardian came up with an interesting little bit of trivia when one reader asked
"Is it true that Albania once barred Celtic defender Danny McGrain from entering the country because he had a beard?"

Danny of course was voted onto Celtic's Greatest Team by the fans

Very nearly, was the answer, as communist Albania frowned at all facial hair under its leader Enver Hoxha, who had made beards illegal before Celtic were due to travel for their 1979 European Cup first-round first leg tie against Partizan Tirana. The owner of a fine-follicled face-hugger himself, McGrain was understandably anxious before the trip, recalling that "there was a lot in the press about beards being banned there."

As it transpired, no one told McGrain to shave it off and he went on to play in a 1-0 defeat. "I would have done it if they had asked, but I had actually seen a few people with them," added the Celtic legend, whose side subsequently ran out 4-1 winners in the return game. "It was a little intimidating too because when we went outside there were only men in the streets and no women to be seen, but there was no bother at all."

Right-back McGrain went on to win 62 caps for Scotland, before moving into management at Arbroath, where his fancy chin-warmer came to prominence again. "I'll never forget how the fans took to Danny McGrain and his beard," recalled then-chairman John Christison of the so-called 'Danny McGrain's Bearded Army'. "It was crazy - but brilliant. They would all wear their own beards and we had 700 T-shirts printed up. They sold out in three days."
