Maybe KY is viewing a bootlegged DVD or something...or perhaps watching the film in another country where Clemenza's 'Hitler' statement is somehow edited out and this 'pe pe ramune' thing inserted in its place.

Whatever he's watching, it is not The Godfather in its original form, because the Hitler at Munich line IS there.

Oh, and KY...to understand fully Woltz's 'bandleader' line, you may want to go back to early in the film and listen to the story Michael tell's Kay about their relationship with Johnny Fontaine.
