For Joan it was most likely that magic moment back in '63 all over again. For most of the crowd it was most likely the words of the very best...and the way he delivers them, although Bob's guitar player gets a rousing "yes" where he really shines ( why couldn't he have drawn that out a bit longer. It's delicious).
But for Bob, I can see him thinking about how he can't wait to hear what his guitarist has cooked up.
Joan is in his way, probaby, buy Bob sure is keeping an eye on his guitar player.
