In the 6/8 thread, thread creep began on different fingers people used to play 3 finger banjo, and/or clawhammer. Given that the thumb on the fifth is so central, does anyone know of anyone who plays (played) without the thumb -- either due to loss of thumb by accident, or just to do it? Pure speculative interest (I have both thumbs, though one is often in my mouth when contemplating my lack of talent).

yours, Peter T.
