Wonderful arrangement and beautifully played!
I just tuned my baritone back to plectrum tuning again last night. I tried it a few years ago and it didn't stick, but it might this time. Have you seen any of Rob MacKillop's videos of plectrum banjo music? Some lovely stuff. His CD Of plectrum banjo music is very worthwhile.
I am going to use this tuning for strumming also. But some of the instrumental pieces I collected before seem more within reach now.
I just discovered Sandy Weltman's site this evening. Great stuff.
