Try JOHN BURKE'S "Old Time Fiddle Fiddle Tunes for Banjo" (AMSCO MUSIC PUBLISHING COMPANY)in their "Personal Instructor Series #1" Mel Bay has a really basic book on frailing by Muller and Koehler which is fine but also has a lot of stupid photographs of hippies and chickens, etc. Actually there many fine books, these two just came to mind when I saw your thread.
