Edit: I can vouch for this.
This is a very common problem in the choir loft. I'm a professional music director and I can say confidently that music at many TLMs is directed by gays. In most cases the laity are completely unaware and praise their highly qualified and capable musicians, but the clergy are absolutely aware in every case I personally know of. It's absolutely scandalous. ... Furthermore, to show how widespread this issue is, it even extends into the annual CMAA Sacred Music Colloquium. One individual in particular is an extremely well-known, flamboyant, active, practicing homosexual who is frequently described by others at the colloquium as "absolutely oozing gayness." His lifestyle and flawed beliefs are known to all involved. Yet he is invited to play, conduct, sing and teach at this colloquium regularly. Others at the colloquium just shrug it off because he is such a talented and respected musician who leads the music program at one of the nation's largest Episcopal parishes.
