He was the Guv’nor. The self-styled hardest man in Britain. For years, Lenny McLean was known as the UK’s most fearsome bareknuckle boxer, undefeated in some 3,000 fights. In later life he began a new career as an actor, with a defining role in Lock, Stock and Two Smoking Barrels.

If your name’s not on the list, you ain’t comin’ in. Got it?
