‘Yoko One was one of the most boring artists I came across, but she had the ability to put people into a state of expectancy that didn’t always result in a satisfactory outcome. I went to a happening at Conway Hall. There were rows of seats all occupied with people, and she started at the front on the left and whispered something in somebody’s ear. They whispered the message in the ear of the person next to them and it went on person by person, row by row for 30 minutes, until it reached the last person at the back of the hall. Then that person went over to Yoko and whispered the message in her ear, and Yoko stood up and said “Thank you” and walked out.’
