With Travers's agreement, Grossmith sold the rights to "A Cuckoo in the Nest" to Walls, and the play opened at the Aldwych in July 1925. The leading lady was Yvonne Arnaud, and the two leading men were Walls and Ralph Lynn. They were supported by a team of players who became part of a regular company at the Aldwych for the rest of the 1920s and into the 1930s: Robertson Hare, Mary Brough and Gordon James, joined in subsequent productions by Winifred Shotter (in place of Arnaud) and Ethel Coleridge. The play was an immediate success and ran for 376 performances.
