Thanks so much everyone for the helpful suggestions.

I haven't been a choir member since my days in the Oberlin Musical Union (also known as the Musical Onion, because what we do to the music makes you cry...) Here in Washington, there are so many really good, classically trained singers that most of the non-church choirs want people who can sight-sing and are open by audition only. Anyway, thinking of the joy that the MU gave me, it reminded me that as an Oberlin grad (College of Arts and Sciences, not the Conservatory), I might be able to find someone from the Con through the alumni network! I'll start looking around - again, thank you all.
