Input: Question: How many other operas did the composers of Patience write? Passage:In September 2005, Ball made his New York City Opera debut as Reginald Bunthorne in Gilbert and Sullivan's Patience. He spent the first quarter of 2006 on complete vocal rest, following the illness that caused him to leave The Woman in White on Broadway. By the middle of July, Ball had taken part in the Royal Court Theatre's celebratory performance of The Rocky Horror Show. He took a leading role in Kismet in June and July 2007 for the ENO, and appeared on Channel 4's Richard & Judy on 22 June 2007 to promote this production. He then appeared as the solo artist in a controversial 'Musical Theatre' Prom on 27 August 2007 for the BBC at London's Royal Albert Hall. Ball performed a wide range of musical theatre numbers, including several by Andrew Lloyd Webber. The show was broadcast live on BBC Four, as well as on BBC Radio 3.
