Reading all of the other DRs choices for favorite flop shows makes me hang my head in shame for not mentioning them: MERRILY WE ROLL ALONG, ASSASSINS, DEAR WORLD, GREENWILLOW. All of them favorites containing some of my all-time favorite songs, too.
Yes, ALL AMERICAN was a flop (80 performances), Charles Pogue, as was HAZEL FLAGG (though HAZEL had something of a run, it still closed in the red after 190 performances).
