HeyaPinetop, thanks! Seeings how my grandma was a Ewing, I might hafta look that fellah up!:-)
Seriously, I appreciate the info and have seen capos at Elderly and also I think black mtn has them, from whence came my lovely 56. I will check out the book you mentioned, too. I love playing some of the Shaker tunes, the ones I know, need to learn some more!
