I don't know how it would be for banjo, but I think "Lover's Waltz" is beautiful on fiddle, as well as Ashokan Farewell. What are some songs you like that you could do instrumentals of together?Devil in the Garden would be fun.
Ask Sandy or Caroline Paton of Folk Legacy Records to tell you about musical courtship. Sandy posted their story on a thread somewhere this summer. They've been at it since the 50's.
Oh, and my dad, who is still pickin' a banjo at 82 is darned handsome and damn cute, Spaw!**BG**
