The Sydney Symphony Orchestra was the orchestra at the ceremony and performed most of the works in the program, although some pieces performed by the Melbourne Symphony Orchestra was noted in the program and CD. It came to light in August 2008 that the Sydney Symphony mimed its performance during the opening ceremony to tracks prerecorded by both orchestras, after an incident at the 2008 Opening Ceremony revealed that a girl lip-synched a song and used another girl's voice. All performances were recorded in either the Sydney Opera House Concert Hall or Studio 301, Sydney. All voice artists performed live.
