Interesting cast of characters! In addition to the guys mentioned above, the two pictures (Scott's and the the one PHL_Mob posted above) show a lot of other SP characters either loosely or closely affiliated:

-Anthony Borgesi
-both Ray and Eddie Wagner
-Mike Emma (Mousie Massimino's half-brother)
-Sonny Mazzone (Stevie's brother) and another Mazzone nephew who is the son of a Mazzone and a Grande
-Snitch Frangipanni

I gotta say, I wouldn't want to get into a balls and strikes argument with Sonny Mazzone or Anthony Borgesi.
