I heard it was a gambino capo he was with. Can’t remember the name.
I asked this question a while back cant find the damn thread... but i think ur thinking of Bobby Cabert he was gambino skipper that Pesci was hangin w and hes the actual gangster who said that scene that won him an Oscar in Goodfellas the “Funny How†scene at the Bamboo.. i read Pesci either told Scorsese the story and he told him to use it or he improved it and Marty was blown the fuck away...
Altho the capo i think Pesci was with was Joe Dente of the Genovese? Altho in that Jersey Boys movie it was Gyp DeCarlo...PB would know im pry dicking this up, but i know for Bobby Cabert the Gambino skipper is who he got that scene from bc he was a fuckin lunatic
