Not a Stones show, but I had two tickets for a Clapton outdoor gig about 20 miles from where we live and it was on a Sunday evening in the summer. During the afternoon we had a leisurely walk with the dog got home and had a few spliffs in readiness and then promptly both nodded off. Woke up at exactly ten minutes after the start of the gig (accounting for support acts) and feeling still well stoned and the journey ahead of an hour by car...rolled another joint and thought @#$%& it! Still have both tickets unused!
