I really don't know what to make of this. It's odd enough that a Jewish man [1] would write a musical number called “Springtime For Hitler [2] (okay, it was for a comedy film [3]) but that doesn't even come close to the cognitive dissonance of seeing it on German television [4] (link via news from me [5]).
Words are failing me.
