The development of foreign relays-particularly from America and middle-Europe-has been
one of the most conspicuous achievements of the B.B.C. engineers. It is good to find, therefore, that foreign relays are liberally represented in the Birthday Programmes. Apart from the Vienna Opera House relay, a " Radio Pot-pourri " is to be relayed front Berlin, the intention being to give British listeners some idea of a popular German programme. And from Budapest comes a relay of Sandor Bum's Tzigane Band-so that we may hear Tzigane music as it really should be played.
