Meanwhile [it was] decided that once I had passed my School Certificate I should be allowed a certain amount of time off for music during school hours. This was unprecedented, and the favouritism was resented by one or two of my class-mates, who considered any music short of Henry Hall or Harry Roy, the ‘pop’ band-leaders of the day, as a mad aberration not to be encouraged.  In retaliation I began proselytising and won quite a few converts to the serious cause.  If I bullied, dragging my heretic friends to the nearest piano and making them listen to Bach and Beethoven, I excuse my presumption in retrospect on the grounds that a successful musician must needs be both propagandist and defence counsel for the composers he loves.
