Cecil Clarke's adaptation for television has been used as the basis for the current revised version. While retaining all the well-known musical numbers, it allows a more fluid production, no longer dependent on major scene changes, and, by omitting scenes incidental to the main plot, has concentrated on the central love story between penniless, unknown composer, Rudi Kleber, who leaps to fame in Vienna of 1911, and the operetta star who first befriends him, Maria Ziegler.
