I watched this video again with sound, on a bigger screen. I now have more guys for you ok Colonel.

Little Vic Orena, Teddy Persico, and Benny Aloi (in that order, L to R) are exiting the Limo in tuxedos in route to a wedding.

the fellow in the black leather jacket, and brown cap, in the hallway is Alphonse (Funzi D) D'Ambrosio

Vincent (Schwartzie) Cascio is wearing the brown leather jacket & (brown checkered sweater). He is short and has grey hair.

Standing next to Schwartzie is Pasquale (Fat Patty) Catalano. He is wearing a black leather waist length jacket with his back toward the camera, and they are in the corner with Schwartzie smoking a cigarette.

As Louie Malpeso (in shades) is walking through the hallway. The older guy walking next to him is Joseph (Joe Notch) Iannaci

Everybody else is blurred or covered. The only other 'possible' guy is Patty Amato (with jet black toupe) walking into the courthouse up the steps (but it may NOT be him). The guy looks a bit short for Patty, who was almost 6' and built big
