Ça Ira (French for "It'll be fine", subtitled "There is Hope") is an opera in three acts by Roger Waters based on the French libretto co-written by Étienne and Nadine Roda-Gil on the historical subject of the early French Revolution. Ça Ira was released 26 September 2005, as a double CD album featuring baritone Bryn Terfel, soprano Ying Huang, and tenor Paul Groves. A full operatic performance took place on 25 August 2006 in Poznan, Poland, and was televised live on Poland's TVP. The project involved the same number of musicians from the concert performances in addition to more than 200 dancers from the Great Theatre in Poznan. There were also period elements of stage design (such as horses, carriages and war scenes with soldiers and stunt performers) and full costumes. Over 500 artists were involved, and the production reportedly cost in excess of €2 million. Performances were held in Kiev on 16 December, and at the Poznan Opera House on 30 and 31 December 2006.
