Most of these guys didn't know one anothers last names unless we had gone to grade school with them and knew them from way back as kids. Many you only knew them by their nicknames.
Interestingly, Joe Pistone said that when Lefty Ruggiero asked him to be his best man for his wedding, he asked him (Donnie Brasco) what was his last name so he could write it on the wedding form. They have been close for 6 years and would speak on daily basis but Lefty didn't know and never care to know the last name of the guy he considers his best friend.
