Lenny used to train at slim gyms in greenwich not far from me many years ago, he certainly was the guvnor alrite a very big and very intimidating man to a young skinny lad,lol, used to walk about like he own the place but he was always very approachable, such a shame after all those years working the doors, money collecting and on the cobbles that he lost his life to brain cancer, just as he was making his money acting. one of my dad's freinds fought him, didnt turn out to well for my dads pal.
