Doing a little holiday banjo arranging and came up with this for 'The Little Drummer Boy.
It begins in the key of G with the low D string as a drone then modulates to D keeping the same drone and the goes back to G and ends.
I will put up a video as soon as my camera's battery charges and I have the time but for now here is the written arrangement. If you want to view it in tabledit form (clearer and with MIDI so you can listen to it but requires a tabledit browser) go HERE.
Here it is in picture form (click to enlarge)...
