READERS' of The Radio Times will remember announcements of the new National Chorus, which is destined to provide a permanent, amateur chorus, the members of which will be at the same time members of the existing amateur choral societies, to perform in important works on a big scale. For some time it had been the custom to get together a chorus formed of parties drawn from some of the big London choral societies, who sang with the professional Wireless Chorus ; but it was felt that the time had come to establish a permanent amateur chorus that could be called upon for the performance of the most important choral works. Ever since the announcement was made the work of giving auditions has been going on, although the actual selection will not begin until the last audition is over. In this evening's talk the full significance of this development, momentous in the history both of broadcasting and of choral singing-for permanent choirs of two hundred and fifty are not formed every day-will be explained, and the first season's work of the new organization will be outlined.
