For the greater part of the twentieth century, Ibbs and Tillett''s concert agency was to the British music industry what Marks and Spencer is to the world of the department store. The roll-call of famous musicians on its books was unmatched, and included such international stars as Clara Butt, Fritz Kreisler, Pablo Casals, Sergei Rachmaninov, Andr Segovia, Kathleen Ferrier, Myra Hess, Jacqueline du Pr Clifford Curzon and Vladimir Ashkenazy, to name but a handful.
