Three sopranos and a big organ

Apologies for my title...:-) *

We had the final (well 2nd for us! ) practice of The mountains shall bring peace, the new coronation anthem, and then performed it in St Peter's.  It's a while since we've done proper challenging choral music, and are pleased that the conductor intends to do similar more ad hoc sessions. 

* watched too many Carry On films in my youth.
