He been asking around for years about how to find those stories. This guy "Al Nero" was sort of "king" of the mobsters favorite piano player/singers.
He also worked at a place in the Bronx called "The Golden Chariot" check that one out. Its mentioned in a few books. He used to get haircuts at Krugmans place "for Men Only". I believe he said it was on the same block as "The Suite".
He knew all those guys very well. You see gangsters for some reason have always loved musicians. They seem to love coming up to you , asking for a song (I once got 100.00 for playing "Stardust") and slipping you money....
I have a few stories (nothing like my friend Al...) If anybody really feels like hearing them....
