I saw the Beach Boys doing a live performance on TV recently - at least those that are still around - I believe two of them have passed away? ... Brian Wilson looked almost comatose sitting at a keyboard - very sad indeed - although a couple of times when the camera zoomed in on him it looked like he played a couple of chords - ... they have a pretty good size band of all young musicians/singers backing them up so it is hard to tell who is actually playing and singing ... but the sound and the energy seemed to be there ...
