'Crammed with ... source material out of the BBC's capacious archives, this book offers a major contribution to the history of music in 20th-century Britain.' BBC Music Magazine '... [It] not only provides an indispensable addition to existing publications but fills a lacuna in British music history of the twentieth-century. This study will remain a valuable source for scholarly enquiry for many years to come.' Tempo 'It is the most compulsively un-put-downable book I have read for a very long time.' Gramophone
