Opened at the Ambassador Theatre on September 29, 1921. Ran 592 performances, to about March 1923. Das Dreimäderlhaus, adapted into English-language versions as Blossom Time and Lilac Time, is a Viennese pastiche operetta with music by Franz Schubert, rearranged by Heinrich Berté (1857–1924), and a libretto by Alfred Maria Willner and Heinz Reichert. The work gives a fictionalized account of Schubert's romantic life, and the story was adapted from the 1912 novel Schwammerl by Rudolf Hans Bartsch (1873–1952). Originally the score was mostly Berté, with just one piece of Schubert's, but the producers required Berté to discard his score and create a pasticcio of Schubert music. Wiki link
