Also, Vito Antuofermo (former boxing champ) was seen briefly in one of the Copa scenes. He turned up in Sopranos as a garbage contractor or strong-arm guy.
Scorsese knew how to pick his extras--everybody (and everything) looked authentic in "Goodfellas." In the introduction scene in Sonny's restaurant, Fat Andy is played by Louis Eppolito, a former NYC cop who was later nailed with his partner, Steven Caracappa, for doing hits for the Lucchese family. In a later scene, the guy that Batts greets with "Vito!" (tall thin guy, beard, chain) is Vito Piccone, former lead singer of the Elegants, an Italian-American doo-wop group that had a big hit in 1958: "Little Star."
