For four decades, the Australian Broadcasting Corporation and Opera Australia have brought some of the most unforgettable operas to the small screen. This program marks the 40th anniversary of that association with a gala live performance, as well as archival footage from the 1960 production of "The Marriage of Figaro," Baz Luhrmann's celebrated staging of "La Bohème," and much more. Joan Sutherland, Donald Smith, Joan Carden, and others appear. 89 min. Soundtrack: English Dolby Digital stereo.
