The town hall underwent major renovation between 1952 and 1958, and it was also internally restructured to allow air-conditioning and soundproofing to be installed. Singapore’s national song, “Majulah Singapura “ , was performed for the first time at Victoria Theatre in 1958 after the major renovations. In 1979, the Memorial Hall was renovated again to accommodate the Singapore Symphony Orchestra (SSO), at which time it was renamed the Victoria Concert Hall. Additional works up to the 1980s added a gallery to the Concert Hall, increasing seating capacity and enclosing the second storey balconies on the front and back facades with glass.
