In August 1914 Jerome Kern wrote a song to interpolate in a Broadway musical imported from Britain. The song is "They Didn't Believe Me." It is the first modern ballad, just as Irving Berlin's "Alexander's Ragtime Band" is the first of the uptempo classic American popular songs. Sinatra never recorded "They Didn't Believe Me" but someone taped his live performance of it, in the late 1940s, crooner style, screaming bobbysoxers and all. Here 'tis. The repetition of the last clause is Sinatra's innovation. You might also check out Johnny Mercer's swinging cover of the same wonderful song.
