 The two "Works" albums were supported by North American tours which lasted from May 1977 to February 1978, spanning over 120 dates.Some early concerts in 1977 were performed with a hand-picked orchestra and choir, but the idea was shelved after 18 shows with the band due to budget constraints.The final concert with the orchestra and choir took place on 26 August 1977 at the Olympic Stadium in Montreal that was attended by an estimated 78,000 people, the highest attended Emerson, Lake & Palmer concert as a solo act.
