It's interesting to see all this (and compare to our choir). Thanks for sharing.

Around the time y'all were having these discussions, what did the "shape" of the Quire look like? Approximately how often did you do gigs (and were they evenly distributed or lumpy)? How many singers were there, and what proportion tended to be available for any given gig on average? Did you maintain standing repertoire, or was music prepared for one gig and then set aside? Were you dealing with a wide range of skills and/or interest levels, or was there a common understanding of baseline expectations (have these skills, make this proportion of rehearsals, do this homework, etc)?
