I think that I get dmg's train of thought. I guess if we are to strip MK of his guitar playing (his strong asset) and of his voice (his identifiable but not so strong asset) we have nothing left. A physical presence is simply not enough. Maybe, like Billy Joel, he will compose musical pieces and let others interpret them. But it will not be the same. But I am growing old and I really don't care about these things as I used to. Play or not play.
After all we have Joan Baez or Metallica that can sing BiA.
vgonis - I wasn't expecting that MK would not play guitar at all, or not sing with that very beautiful, warm voice, rather that when his fingers eventually get a bit stiff, due to old age, he will still play beautiful melodies for us, just as he does now, but probably not the long intricate solos that we were accustomed to!
BTW I didn't realise that you were so old! I had in my mind a young flibbertigibbet in his 30s!
It's me who is the really old one, so, of course, I am completely comfortable about anything MK decides to do, except that he keep playing for us and writing beautiful songs!
