I saw it with a different ending *SPOILER*
Maybe instead of "different", I should say "re-edited". Admittedly, I saw this at a second-run house. The original ending had the wounded Tommy stagger to his old neighborhood with the ledger, looking up and saying "Joe!" when the boys come up and start beating him to death. Stealing his shoes and watch and we see the title card telling us that it's now 1973. Then the credits start rolling. What I saw at the s-rh: Tommy staggers to the old 'hood, says Joe's name, then the screen goes black and the credits start to roll. I'm guessing that, after seeing the box-office take, the studio re-released it with Tommy's death edited out so that they could get a sequel made.
