I think you need to contact someone a bit closer to Ian 'Jock' Manuel from Hull, someone like Gill Pidd or even Mike Waterson, possibly John Curtin from Leeds

Jock was a real character who always had anumber of big hard drinking lads with him, i remember him from Cleethorpes FF on the pier

he was bothy ballad exponent, a good one!

Saw a documentary film on Yorkshire TV about his son, who became Mr Britain (body building)which was enlightening and moving (each to his own)
