I've not only heard of BOY MEETS BOY, Sean, we played a song from it at our (gay) wedding. A close friend, Joanna Seaton, was in the New York cast (though I'm not sure she was in it on opening night).
Confining myself to "odd" choices, does ROAR OF THE GREASEPAINT count? Although it spawned several pop hits, it only ran for about six months on Broadway and, to my knowledge, has never enjoyed a major revival.
