Gershwin wrote "Porgy and Bess" in 1935 and "Rhapsody in Blues" in 1924, but way back in 1922 he wrote a one-act opera for the Broadway stage.

The whole thing lasts less than 20 minutes, at the end of which the woman shoots her man for doing her wrong, and then finds out that he ain't done her wrong at all, but she was tricked into thinking he had.

It's sort of like "Frankie and Johnny" combined with "Otello."

I was looking to see if there were any clips from the opera, and I'll be danged if I didn't find one from the very show I saw:
