They probably aren’t going to be singing much anything anymore.
Mick Jagger is 78. Keith Richards is 77 (and likely undead).
Ronnie Wood is a chipper 74.
I stopped watching them live around 15 years ago. You dont like watching your idols look old and weak. Same reason why I couldnt watch Metallica now because Hetfield lost his voice. Back in the day when I was a kid, Hetfield would YELL at you, not “sing”.
