Sir Alexander Mackenzie, who was one of the oldest and closest of Irving’s friends, had much to do with him in his productions. He composed the music for Ravenswood and Coriolanus. At Irving’s burial in Westminster Abbey a part of the latter, the Marcia Funèbre, was played whilst the coffin was being borne from the choir to the grave.
In addition to these important works, Mackenzie wrote the music for Manfred, which Irving intended at one time to produce. He was also engaged on the music for Richard II., a large part of which was completed when the play was abandoned owing to Irving’s serious illness in 1898.
Mackenzie in an “interview” shortly after Irving’s death, told a pretty story of how the end of Ravenswood had been changed. Irving had arranged that the last scene should be the waste of quicksand, wherein Edgar was lost, seen in the cold glare of moonlight—suggestive of misery. When, however, he heard the music—of which the finale is the love motive in a triumphant burst—he seemed much struck by it. He said nothing at the time, but the next morning the composer received a letter thanking him for the hint and adding:
“And the moonlight on the sea I shall change to the rising sun.”
