Allen Ginsberg reading Howl at the Royal Albert Hall, 1965. Though my favourite moments were when Harry Fainlight used a bow and arrow to loose his poem into the audience, and when the lady cinematographer was whirling her 16mm Bolex around her head, capturing zip panoramas of the oval interior of the Hall.
This was my first personal experience of the American/British/European ‘intermedia’ scene. It was part poetry reading, part party, part happening, and it presaged the whole Hippy thing (flowers given away outside Albert Hall). It decided me on the audio-visual ‘gesampkunstwerk’ route that became the central theme of my Diploma (DipAD) essay the following year.
