I am preparing a radio series about tolerance, intolerance and political incorrectness in music over the past 100 or so years. The kind of songs I have in mind are Don't Bite the Hand That's Feeding You (First World War), The Dumber They Come The Better I like 'em (1920s),Smoke That Cigarette (1940s), Teacher's Pet (1950s), He Hit Me, It Felt Like A Kiss (1960s), Jewish Princess (1970s) and so on.

Ideas anyone? The more obsure the better. Songs that are intentionally offensive interest me less than ones which have a sort of weird innocence of their time (eg Love is Like a Cigarette).
