I thought that they kiss was cute and funny...I certainly didn't get the impression that it was supposed to be believable.
Promises, Promises is a 1968 musical in which Hayes plays a low-level corporate nebbish who lets his on-the-make bosses use his apartment for trysts with the gals in the secretarial pool. He has three assignments in the show: He has to be funny and nervous; he has to manifest a crush on his costar Kristin Chenoweth; and when he’s excited, he has to burst into song. And you’re telling me that being gay is an impediment for this particular role? It’s practically a prerequisite! Besides which, I have to ask: Mr. Setoodeh, are you new here? This is Broadway musical theater. If you have a serious problem with gay actors playing straight roles, you’re going to have a lot of free evenings on your hands.
