I don't suppose an itinerant Tenor and Soprano would have made the difference?
The sops and alts were losing it yesterday (prolly due to poor continuity of sops at recent rehearsals) so sadly that's unlikely to help, but thanks for the suggestion/offer.
We'll fall back on some dead-certs like Locus Iaste or Adoro Te.
I look forward to seeing you Q, I've often wondered what a fellow forum member looks like.
