In 1900 the theatre was purchased by the powerful J.B. Sparrow Theatrical and Amusement Co which entrusted its management to F.F. Proctor. During the 1900-1 season and the first half of 1901-2 chamber music concerts, with local artists and guests, were held on Sundays, with matinee and evening performances. The J.-J. Goulet and Alfred De Sève string quartets were among the performing ensembles. The series was interrupted when the organizer was sentenced to one hour's imprisonment for violating the municipal by-law concerning the Lord's Day Observance Act. Among the orchestras that played there were the Goulet MSO 1907-10, the Canadian Grenadier Guards Band 1920-3, and the Montreal Orchestra 1931-41. The theatre also presented Marian Anderson, Ferruccio Busoni, Walter Gieseking, Sergei Rachmaninoff, Paul Robeson, and numerous other celebrities. Ca 1924 it was controlled by Theatrical Enterprises. Consolidated Theatres and United Theatres were the owners when it was demolished in 1963.
