Early in 1919 Major Davies undertook what was to be his last major commitment before leaving the Service. On the morning of the 19th February 1919 a memorial service for members of the Royal Air Force was held in Westminster Abbey and for this he composed 'Memorial Melody' for strings, drums and organ. In the evening of the same day a public concert was given in the Queen's Hall featuring bands and choirs of the Royal Air Force. The songs that he had found to be most popular with the men during his work on the ill fated RAF Song Book were sung and Captain Claude Powell conducted the Royal Air Force March Past.

Very soon after this Walford Davies returned to civilian life to become Professor of Music at Aberystwyth University College, Musical Director of the University of Wales and Chairman of the National Council of Music. He was knighted in 1922 and became Master of the King's Music in 1934. At the time of his death in 1941 his name was one of the best known in British music — this was largely as a result of the weekly series of broadcasts on musical topics he had given from 1924 onwards. His gift of communication attracted a wide audience and for many people it is as a broadcaster that Walford Davies is remembered.
