A nightingale sang
On 19 May 1924, the BBC broadcast outdoors for the first time an extraordinary duet live from a Surrey garden, featuring famous cellist Beatrice Harrison and a male nightingale which responded with its own song in the woods around her home in Oxted, Surrey. It was so popular among listeners that the performance was repeated every spring for the next twelve years. The last performance was on May 19 1942 when Allied bombers flew overhead on their way to raids in Germany. The engineer realised a live broadcast cut alert the enemy and he cut the signal.
