Roger I had mine 10 years ago and ended up having a triple and OH. Surgery I was given a banjo to learn, as my friend is an after care consultant. He gave me the banjo and he explained that the muscle reactions and the automatic finger movements would in time return, and they have, although I don't play as much guitar as I use to. He said that there would be gaps in my memory and to try to fill them with something new, eg the banjo, not played before, "and like you claw hammer". As said it was slow progress and I was ready to pack it in many times, like Georgiansilver I mostly sing with a copy of the words in front of me as I can't remember even the old songs all the way through. Keep it up and best wishes Oombanjo
