Saw the Rolling Stones back in 2006. Richards looked rough then, but he clearly enjoyed being onstage and playing. He walked over to the side of stage numerous times, smiling and talking to fans. He wasn’t just going through the motions, he was up there putting on a great show and giving 100%.
I saw them in 78. 2.5 hours late, show was over in 45 minutes and then a riot ensued as folks stormed and started destroying the stage. Good times:-)
