 This version in three acts was much more faithful to the original and also included music from Lehár's 1937 definitive version.The KlangBogen Wien Festival commissioned Austrian film and theatre director Michael Schottenberg to rewrite the operetta's book for its performance at the 2005 festival.Although Schottenberg's re-working remains faithful to the basic plot and retains most of the original dialogue, the setting was changed to Vienna in the 1950s.
