Not heard of Paul Sykes? 

Mentioned in the book Legends by Charles Bronson, an A to Z guide of the men Bronson had regarded to be the toughest in Britain. Referring to "Sykesy", Bronson describes him as "a Legend, Born and Bred" and writing: "I first met Sykes in Liverpool in the early 70s and at that time he was probably the fittest Con in Britain. A notorious hard man from Yorkshire, a fighting man in every sense. A lot of people never liked him, perhaps they even feared him but I respected the man for what he stood for." Bronson goes on to relate an incident said to have taken place in HMP Liverpool, where Sykes "allegedly" killed the prison's cat and fashioned it into a "Davey Crocket" style hat, I think you get the gist! 

Sykes had also been billed to fight Lenny Mclean at London's Rainbow Theatre on November 20, 1979, but this fight never materialized. Lenny Mclean, in his autobiography The Guv'nor, later explained: "A week before the off, Sykes went into a club in Wakefield where he lives, got well p-ssed and had a ruck with four doormen. He did them all but one of them got lucky and put a cut above his eye that took eight stitches to pull together" and the fight was off.
