The Don combing his hair at the convention was Tattaglia--nice touch for a pimp! He got machine-gunned with the hooker in his bed. Barzini, as you know, got it on the steps of an office building. Cuneo was whacked in the revolving door. Stracci was shotgunned in the elevator. Given that Clemenza let loose with both barrels of a shotgun in that small space, I wonder how the elevator operator and the other guy could have survived.
