Bit of a silly one, but it's Friday night...
The night before our victory at Newcastle in May 1979 to win promotion to the top flight, Alan Mullery took the squad to a cinema to watch a film to help them relax. What was the film?
Clue: It was a recently-released comedy.
Won 8 games in a month (all the games we played). I think it was March. Only equalled by Bristol City I believe.
(Ignore - someone else already said this!)
