Mike,

Thank you for the info. As already stated, I'm singing in two carol services
on that particular Sunday - so can't manage anything.

[Not to worry, it's a very busy time for all of us!]

As regards the service on this coming Sunday, Costas has sent the music by
post and I'm a bit shocked by the amount there is - though not difficult in
itself, fortunately!! Assume the key signature which includes A flat instead of
the usual B flat is NOT an error?

[It's a LONG Service! But there is food afterwards :-) The key signature is
quite correct, but once you've got used to it, it's not a problem.]

Thursday is the first rehearsal for Holmfirth Choral Society's Christmas
Concert so I'm reluctant to miss it - but might just decide to play truant and
come to the rehearsal Thursday (tomorrow) night IF back from distant places in
time.

[Ditto. But as I'm only working in Malton, I should make it, assuming I'm not
bogged down by Local Authority Finance.....!]
