just been thinking
we used to havea music group at our church, and they would perform at some of the sunday services.
see, in Frank's day, the services were split between traditional and modern, alternating week by week.
when we had Choral evensong, the mornign service would be HC, and another service in the month was an "all age service".
in the HC/modern services, the Music Group would play and sing, (there would still be an organ for most of the hymns, unless they were modern worship songs), DH (not DH at the time!) would also have to play the piano for these services. (i think it was the 11am week that was HC and the 9:30 week that was trad)
It carried on like that for a little while after Nick came, but the music group slowly stopped coming to our church, and seemed to drift to St Mary's (i'm not sure of that fact) - the week we had Choral Evensong became a week where the morning service was modern without communion and singing/music group.
(then Nick made the Choral Evensong communion too, and that did bring people in, but when he changed the times so St Mary's had the afternoon service, he stopped communion, and reverted to a normal evening prayer)
while all this was happening, the morning service was then left with no singing group (and no warning of this), DH used to choose the hymns and would leave the singing group to choose their communion/before service pieces.
then they just stopped coming completely - so that sunday was just hymns and organ twidling through communion.
then DH asked if the choir could do that week as well - which was agreed, and that's why we do every week (including the evensong on the same week)
I'm not sure of the timetable of this, all i remember is DH suddenly telling us we were in attendance on that week, and me losing my only lie-in of the month ! 
I could probably find out for certain by looking over the old music sheets...
anyway, I think it had a lot to do with St Mary's services changes etc etc, and Nick pushing us into being more traditional.
there was a heck of a lot of soul searching among some choir members, too - some wanted to leave (in fact one only stayed because the Archbish came and did a sermon about us all being needed and we should do what we can)
I don't know how our church would have turned out if the choir had disbanded.
It probably wouldn't have been good - only organ every week, no singing group because now they have a service they sing in every week at St Mary's, and noone to organise it if they did.
I still feel like we're hanging on by a thread, though.
I think a lot of people (congregation and outsiders, even the diocese) don't realise how much we've invested in keeping the church up and running - all they see is smaller congregation and less money - I don't think they see the people who have stayed and put their all in (not just musicians, but church wardens and other volunteers) to keep the sinking ship afloat.
So many people left when Nick pissed them off, there are many more who also could have, but didn't.
