...a concert ticket

This concert at the Crystal Palace Bowl in June 1972 was not exactly a washout, but those of us who came unprepared for a not untypical British summer's day suffered a real soaking from a thunderstorm.

The line-up of groups was great: Joe Cocker, Richie Havens, The Beach Boys. But the day was cold and miserable and, as one young attendee reflected, there was a lack of any atmosphere.

The whole concert was apparently filmed, but only extracts of it now seem to be available.

Here is taste of that day: https://youtu.be/uS6m0fN-Ow0
