It is possible to perform "The Ring" with fewer resources than usual. In 1990, the City of Birmingham Touring Opera (now Birmingham Opera Company), presented a two-evening adaptation (by Jonathan Dove) for a limited number of solo singers, each doubling several roles, and 18 orchestral players. This version was subsequently given productions in the USA. A heavily cut-down version (7 hours plus intervals) was performed at the Teatro Colón in Buenos Aires on 26 November 2012 to mark the 200th anniversary of Wagner's birth.
