The New Tivoli Theatre, Sydney, previously known as the Adelphi Theatre and the Grand Opera House, was a theatre and music hall at 329, Castlereagh Street, Sydney, Australia, which was long at the heart of the Tivoli circuit.
It was generally called the Tivoli Theatre and operated between 1911 and 1966.
The theatre was opened on 5 May 1911 as the Adelphi Theatre with George Marlow's production of the The Bad Girl of the Family. The auditorium was licensed to seat 2,400 patrons and was a pioneer of modern cantilever structural techniques. It was the first theatre to have its tiers and galleries constructed on the cantilever principle superseding iron columns to support the front of each tier. The theatre was closed for renovations by Marlow's partner and entrepreneur Benjamin Fuller in October 1915. The auditorium was redesigned by Henry E White to improve sight lines thus reducing capacity to 2100.
In August 1916 the renovated theatre reopened and was renamed by Benjamin Fuller the "Grand Opera House".From 1929 it became the major outlet in Sydney for variety theatre, featuring vaudeville acts. Christmas pantomimes were popular and featured the in demand double act "Stiffy and Mo" (Nat Phillips and Roy Rene).
In 1932 two vaudeville performers Mike Connors and wife Queenie Paul took over the lease of the theatre with their company, Con Paul Theatres, and renamed it the New Tivoli Theatre. The new name was in recognition of Harry Rickards's Tivoli Theatre at 79-83 Castlereigh Street (formerly the Garrick Theatre, Sydney). This period saw the emergence of well known Australian entertainers including Roy Rene and George Wallace. The theatre became famous for its chorus girls, known as "Tivoli tappers.
Tivoli Circuit Australasia Pty Ltd emerged as the controlling organisation from late 1935 a period that saw an increase in imported acts. A high point was the visiting Old Vic Company in 1948 when Laurence Olivier and Vivien Leigh performed there. However restrictions in the war years led to a return of local artists and emerging stars featuring such names as Peggy Mortimer, Dick Bentley and Joy and George Nichols.
