The operas of Harrison Birtwistle (obituary, 18 April) were masterly creations. His individuality as a composer was also reflected in his dress – on the many occasions I saw him at concerts, often quite formal events, Birtwistle stood out, with his baggy trousers, open-necked shirt, no suit and definitely no tie.
