" Early Sunday evening Acker played a set on the main stage while the Stones did their stuff in the club house. It was packed, if you had fainted you could not have hit the floor. At the end of the set Mick Jagger gave a little speech saying that we were running to a timetable and they were going to play one more number then make way for the next band. he referred to the riots at the Beaulea jazz festival the previous year when Acker's fans had wrecked the place when he stopped playing. Mick said that if that happened here the Stones would not be able to play venues like this again. They played one more number whilst we 4 or 5 "security staff " crossed their fingers then after suitable applause the crowd left in an orderly manner, I had always shared much of Mick's musical taste but this was the first time I realised just how good he was at crowd control.
