The Hymn that I know of as 'Jerusalem' contains the immortal words "Englands green and pleasant land" of course and to me is full of national pride as well as religious fervour which could well be suited to a Saints day. It's a lovely tune as well but might be more suited for massed choirs!A bit of Kipling might go down well.
BTW - I'm sure someone told me St George was Italian or Greek or some such. Well, I guess Yorkshire is just as foreign.....(Retreats hastily over the Pennines:-))
Good luck anyway, Joan. I'll be down in Bristol but with you in spirit!
Cheers
