After listening to some of the tour dates this year....compared to the say Vodoo Lounge tour was the last time I saw them in 94 live....they sounded bad off key and out of tune on lots of songs on youtube....at close to 80 I would say its time to hang it up guys. Mick still can move around better than most men half his age...but his voice is going/gone/ Keith missed notes and played sloppy and Ronnie was the only on that seemed to still have it. I think they should have hung it up when Charlie died. They all are worth over 350 to 500 million ......cant be for money . As my friend pointed out this was most likely the last time the last three will play together and hated to miss it but hey im getting old and have health problems myself now.
