Hi Girl Friday,
what a splendid thing to do. I don't know you or Bob but I wish Bob well. I was on a death bed (2X actually) when most of the Johnson Girls (& my singing partner Neil Downey at a different time) came in & sang at my bedside. I joke that when they left I saw the devil & he said that the music was too beautiful & that he now wanted no part or me. It wasn't true but it felt like it. I'm sure it'll do wonders for Bob.
Best of luck to you friend.
Barry
