I have lost count of the number of times I have been asked to play Duelling Banjos. So much that I decided to learn it. I was amzed to find that in the sheet music I bought it only gives the first few bars (The bits everyone knows) and then says that the player should improvise. I took them at their word and worked out a way of playing both parts on one banjo - playing the second part one octave higher. Works fine until someone with a guitar decides to join in. Not like the amazing Mr Smith who plays it with two small banjos joined together at the top of the neck -wonderful
