"The title of this album was inspired by a recording made in Surrey, England during the Second World War, by an ornithologist intending to record Nightingales. The bombers flew over at the same time and were recorded by accident. The recording has been incorporated in 'As Above, So Below'". - Manfred Mann 1975
The recording was made on 19 May 1942 by a BBC sound engineer for the BBC. Intending to capture the nightingale's song he also, by accident, recorded the sound of RAF bombers on their way to attack Mannheim, Germany. In that raid 197 planes were dispatched and 12 were lost.
