TB, I like the Paragons' music too. I was looking for a live performance by them thinking they may have been part of a NY doo wop show, but only found them singing in what appeared to be a coffee shop, so I didn't post the link. Now, I'm thinking I should put on Mean Streets again so I can listen to all this great music. That scene where Charlie is drunk makes me dizzy. Scorsese has them singing the Neapolitan song at the end called O' Marenariello. I Have But One Heart as you stated which is in The Godfather film.
Scorsese NEVER disappoints with his selection of music in his films, ESPECIALLY in Goodfellas.
