Thank you for your encouraging reply, Antony-Paul - much appreciated!
I shall certainly look out for a copy of the book you mention.
[Edit - just bought it on Amazon]
(Also, some of the publications by the BOC look interesting, on the Lulu site.)
Thanks for the 'heads up' about the church services. The nearest one to me is Doncaster I think. It's about an hour and twenty minutes away, but I have friends there I could stay with.
Looking forward to learning more...
