Clarification: Austria-Opera-Alceste story - Article Photos 3/3

In this undated picture publicly provided by the Vienna State Opera, Joseph Kaiser as Admete performs during a rehearsal at the Vienna State Opera of Christoph Willibald Gluck's “Alceste" . Two tenors in the same role at the same time _ what could have been a recipe for disaster turned instead into a delightful operatic performance of Christoph Willibald Gluck's “Alceste,” with Joseph Kaiser's sudden voice lost led to a bit of successful improvisation. The audience groaned at the announcement that the Canadian tenor was not fit to sing Friday Nov. 23, 2012 and applauded only dutifully when told that Charles Workman would be singing from the orchestra pit with Kaiser acting out the role on stage But it worked.
