Spot on.
"But middle-aged fans and pensioners have been barred from the guest list because organisers fear they are not spritely enough to dance, sing and cheer."
If the Stones plan on succeeding as a band, they will surely fail with polarizing decisions like this one.
People aged 45+ compose their central fan base, and alienating them like this is just insulting.
I grew up listening to the stones in the 60's, 70's and 80's and although I would hardly call myself a diehard fan, I would be pretty out out by this. I'm only a couple of years over the limit but it is people my age and older that form the bulk of their fan base. This to me seems to be cutting off one's nose to spite one's face.
