I saw the Stones in concert about a year ago when they came to Hong Kong. They sounded great but they really looked old. Not sure if you've heard this nickname: Strolling Bones. Mick, to his credit, was on the move throughout the concert going from end to end of the stage.
A cousin of mine had his own rock band in the 60s when he was a teenager. A few years ago the band reformed to play at our family reunion. Imagine 50/60-something guys jamming on their electric guitars with their reading glasses perched on the tips of their noses! It was great fun.
