Thanks everyone for your support and encouragement!
I've been thoroughly enjoying getting to grips with it for the past couple of days, here is a little video (with a fair share of bum notes!) to give you an idea of what it's like:

@Gloscon: Thanks that's very kind
@Chas: I accept your challenge!
@Voyager: I've got Paul Hardy's regular tune book which has given me plenty to get started on - I'll check the Christmas one out later in the year
It's good to hear others have used their concertinas in worship - Chris Algar was very pleased to tell me that mine is good Salvation Army stock so has pedigree for that kind of playing!
Thanks all,
Rich
