I think the range of expression available on guitar is much wider. Try playing a convincing version of Bessame' Mucho or The Girl from Ipanema on banjo....see what I mean? Now, when it comes to Turkey in the Straw, I admit the banjo wins hands down. But have you ever heard of using Turkey in the Straw to coax somebody into the sack? I mean, outside of Catspaw using it on the local girls when he was at Berea?
