William Alexander Houston Collisson (20 May 1865 – 31 January 1920) was an Anglo-Irish priest, writer, organist, pianist, impresario, and composer, mainly remembered for his long collaboration with Percy French.
In 1899, he was ordained a priest at Truro Cathedral in Cornwall and subsequently served in different parishes in England.
[2] In 1906–7, he took time out from his London parish to do a solo tour of Ireland as a singer and performer on piano and organ in his own compositions and those of Percy French.
[3] They often appeared together on stage, including regular performances in London and touring North America in 1910.
Collisson also wrote operas to which French contributed the libretto, including The Knight of the Road (1891) and Strongbow (1892).
