To add to the fun:

I'm an opera fan. "Raging Bull" opens with the intermezzo from "Cavalleria Rusticana" by Mascagni. One of the best-known operatic pieces ( you heard it at the end of GFIII). But then, Scorsese (clever fellow) puts in two very obscure (in America) Mascagni pieces: the barcarole from "Stephano" (color sequence after Jake gets married); and the intermezzo from "Guglielmo Ratcliffe" (when Joey has his sit-down with Tommy Como). Plus, they're performed by an equally obscure orchestra: Orchestra Municop of Bologna, conducted by Arturo Basile. Couldn't find either anywhere except for the sound track CD of "Raging Bull."

My favorite music match in "Goodfellas" is the opening of Billy Batts' party at Henry's bar--"He's Sure the Boy I Love" by the Crystals.
