In 1814, Beethoven revised his opera yet again, with additional work on the libretto by Georg Friedrich Treitschke. This version was first performed at the Kärntnertortheater on 23 May 1814, again under the title Fidelio. The 17-year-old Franz Schubert was in the audience, having sold his school books to obtain a ticket. The increasingly deaf Beethoven conducted the performance, "assisted" by Michael Umlauf, who later performed the same task for Beethoven at the premiere of the Ninth Symphony. The role of Pizarro was taken by Johann Michael Vogl, who later became known for his collaborations with Schubert. This version of the opera was a great success, and Fidelio has been part of the operatic repertory ever since.
