Everybody in the unlicensed fight game knows that only one man has the honour of being titled 'Guv'nor' - and that man is Lew 'Wild Thing' Yates.
Yates began boxing at the age of six, and as an adult he was ruthless in pursuit of his dream of becoming world heavyweight champion.
But when his licence was revoked following an assault on a referee, he turned to unlicensed boxing. By day, Yates pounded punchbags and the streets in an effort to reach the peak of physical fitness as he prepared for his epic battle with Roy 'Pretty Boy' Shaw.
At night, he pounded gangsters and drug dealers foolish enough to take him on in the nightclubs where he worked. Wild Thing documents how Yates rose to the top of his bloody profession.
When it comes to his fighting ability, he doesn't need to boast, brag or exaggerate.
With Lew Yates, what you see is what you hope you're never going to get.
This is his remarkable story.
