Tower Pier, London.

Strange inflated structure is constructed on the roof of a building - a clear plastic marquee with large air cushions inside. Lots of children with funky 1960s hairdos play in the precursor to the bouncy castle. They clamber around and bounce on air filled structures. Narrator talks of how in the olden days hippies would call this "a happening." The inventor is Jeffrey Shaw and he calls his installation "the Movie-Movie mark 1". It is a "response structure" that requires participation from those who visit. A kind of art work I suppose.

Cuts exist - see other record.
