John McLachlan’s article on Terry Riley makes me think of my debut at the Royal Festival Hall in June – at last as I am 65. The London Sinfonietta were performing Riley’s In C. There were some spare seats at the back of the band so I went and sat in one, whipped out my C harmonica and joined in. They could have come and removed me and made a scene but the conductor gave me a thumbs up when he spotted me. There are not many orchestral pieces you could do that in. (I had gone there to take part in Billy Bragg’s Big Busk so my second RFH performance took place almost immediately!)
