Eric Coates (1886-1957) is perhaps the most familiar name associated with British light music. Sir Charles Groves said that 'his music crackled with enthusiasm and vitality. He could write tunes and clothe them in the most attractive musical colours'. Coates won a scholarship to the Royal Academy of Music, and from 1912 to 1919 he was principal viola of the Queen's Hall Orchestra under Sir Henry Wood. He also played under such conductors as Elgar, Delius, Richard Strauss, Debussy, and Beecham. It was, however, as a composer of orchestral music that he found his greatest success. Beginning with the Miniature Suite, written for the 1911 Promenade Concerts, he forged an enviable reputation as a composer. By the 1920s and 1930s, he was one of the most popular and highest-paid British composers, with a string of popular works flowing from his pen. Coates' music has become indelibly entwined with such popular radio programmes as the BBC's "In Town Tonight", which was introduced by the 'Knightsbridge' March and "Desert Island Discs" whose signature tune for the past forty years has been "By the Sleepy Lagoon". Perhaps his most memorable work was his march for the "Dam Busters" film. Michael Payne traces the changing fortunes of the career of the man who composed some of Britain's best-known music. In many ways, Coates' story is the story of British light music, and Payne's study offers a fascinating insight into the heyday and decline of the British light music tradition.
