Performance, art, Pink Floyd and a QC

I am currently writing a few memoir pieces, set in late-1970s London, during the period of my life when I was involved with performance art. The artist was sculptor Paul Wright, who was also part of the design team for the Pink Floyd stage shows, and a QC, who was the ‘art object’, taken all over London in various disguises. The event was photographed and then recorded on a Rank Xerox colour copier, a new process at the time. I was the helper, sometimes writer of set pieces, and occasional performer. The QC, a good friend, is now dead, and the full story, which will reveal his identity, can be told for the first time. There will be a London exhibition of the work in September 2016.
