I don't recall 'Wise Men Say' being sung at City in the 70's. Very few clubs had there own songs in those days. The obvious one was Liverpool, YNWA, and every club sang that is if it was there own. City terrace chants in the 70's, like most clubs, were copied off each other, and quite simple chants. Mostly about getting your head kicked in, one song was Jim Reeves 'Distant Drums', sang 'We hear the sound of distant bums, over there, over there, and when they come......' Mary Hopkins, 'Those were the days', another I remember was 'Soley, Soley' but sang 'Oh, David Sunley, repeat...' Forget which group sang it. Cliff Richards, Batchelor Boy,
Also Peters and Lee's 'Welcome Home' I thought that would catch on. It was first sung, probably in the 80/90's when we moved back into Kempton after a sustained period of the stand being closed. That was about the only original song we had. It never caught on. I do remember 'Wise Men Say' being sung in the Kempton right at the back end before we moved to the KC but certainly not in the 70's.
