Hi Amy
It's a funny thing, but there does seem to be a bit of a herd mentality when choirs choose repertoire.
A couple of years ago you couldn't go anywhere without having the Mozart Requiem sung at you....
The following Christmas the Vivaldi Gloria was all around....
Last year Haydn's Creation was favourite...
This year (so far) I've been invited to two Brahms Requiems, and to FOUR Faure Requiems! And no, I don't just go to Requiems
I don't know of a Poulenc anniversary, but someone may prove me wrong.
Cheers
