In June and July 1967 the Hamburg opera ensemble toured North America, with visits to the World Exposition in Montreal (Canada) and New York. In addition to six modern works (including Jenufa and Mathis der Maler) the programme also featured Der Freischultz. In order to avoid any "stylistic hiatus" with the modern operas, the company decided to perform a concert version of Weber's work. The tour concept was an enormous success, with tickets being traded at black market prices. In August 1967 the company made the first of 13 recordings for television. Commissioned by NDR, the film and TV company Polyphon made use of original productions from Hamburg State Opera. Director Joachim Hess (opera director at Hamburg State Opera from 1967 to 1972) adapted the stage versions to the requirements of television. Made in January/February 1968, Der Freischutz was the third of the films to be released.
