Thanks everyone, so much for their help.
I had already milked the DT for everything I could find but the extra links are great, thanx Petra. Even Pedantic Tim and the illustrious Murry, thank you for your finer points.
I'm still looking as the performance is on the 21 of November but thank you all for your help so far especially Dulcimer.
PS Moira, I had intended to fall back on a Mummers play if I cant find enough music. (great minds think alike!)
thanx again Bo
