If they were all 10 years younger I would say most definitely they would reunite for one last cash grab tour. Chris could not do it. She could not sit and play keyboards and her voice is pretty much gone
Women lose their voices before men in old age. We saw her struggle with vocals and practically not play keyboards during the last tour and with BuckVie. John was dragged through the last tour. I know Mick and Lindsey would do it without question though.
Getting old sucks. We must appreciate Chris overcoming her fear and coming back to the band for a few more years. Although we all had high hopes for a new album and tour. But we did get Buck/Vie which was a real treat.
