Charlie Watts has a reason for not wanting to play outdoors--the wind makes his cymbals move.
And no one thought to put up screens to keep him from being disturbed by the elements? No one thought to enclose the sides of the stage so that the wind wouldn't be a factor? And how many other drummers complain about such things? I've never heard of this.
Anyway, who cares? The Rolling Stones couldn't be more irrelevant than they are right now. And yet, everyone is so fanatical about seeing them stumble through the same hits every time they go on the "final" world tour.
