I know he met Joseph Magliocco.. Colombo and Persico (obviously)

I remember Mike saying that Sonny met Carmine Lombardozzi, I think it was at the Copacabana. With Sonny being 101 it's interesting to know that he knew the generation that didn't make it past the late 1930s-1950 , I assume by 1938 / 39 he was already associated with the Colombos
