I then went to Amsterdam to conduct Oedipus at the Concertgebouw, which was celebrating its fortieth anniversary by a series of sumptuous musical productions. The fine Concertgebouw orchestra, always at the same high level, the magnificent male choruses from the Royal Apollo Society, soloists of the first rank - among them Mme Hélène Sadoven as Jocasta, Louis van Tulder as Oedipus, and Paul Huf, an excellent reader - and the way in which my work was received by the public, have left a particularly precious memory that I recall with much enjoyment.
