Clinton-Baddeley he wrote a pantomime for the Festival Theatre at Cambridge, and two comic operas, the second of which, "Jolly Roger", ran for six months at the Savoy Theatre in London, with a cast headed by George Robey.He composed an elaborate score for Basil Wright's documentary film "The Song of Ceylon" and the concert overture "Agincourt", commissioned by the BBC in celebration of King George V's Silver Jubilee.
