Had they met on the streets of London in their 1960s heyday, the result would undoubtedly have been violence at its most extreme.
But yesterday a small yet distinctive group of superannuated gangsters and their henchmen put bitter old rivalries behind them and came together to mark the passing of one of their own.
They were among more than 1,000 faces who attended the funeral beneath leaden skies of 69-year-old Joey Pyle, a man who uniquely ran with both the Krays and the Richardsons.
Perhaps because 1960s gangland London has become so mythologised, it seems almost surreal to me that this postscript occurred last week practically around the corner by Morden Park.
