Hyde Park, London.
Brief establishing shots of Hyde Park on Summer's day, boats, couples on grass, etc. Var. good shots of long haired types (hippies) sitting round a stage erected on the grass in Hyde Park, listening to the playing of the Jethro Tull Group (no sound). Presumably this is some kind of pop festival. There is some groovy dancing going on. There are a lot of people there. Some nice C/Us of members of the crowd. At one point we see a middle aged woman who looks very out of place standing up in the crowd.
Most sit and listen, some give impromptu dances. Various poor shots of the Jethro Tull Group playing and also Roy Harper playing guitar.
