I've got friends in the Columbus Gay Men's Chorus... I went to their "Joy" performance last winter (might again this year, dunno), and there were all types of people there, not just gays. My straight brother went with me, for one 😉 I saw quite a few hetero couples there as well. It was held in a church, was a very professional performance, and it was honestly one of the best performances I've seen to date. Just because they're gay, doesn't mean they are not *awesome* singers/musicians (many would say the inverse).
