In his early Munich years Busch's attempts to write libretti, which are almost forgotten today, were unsuccessful. Up to 1863 he worked on two or three major works; the third was composed by Georg Kremplsetzer. Busch's "Liebestreu und Grausamkeit", a romantic opera in three acts, "Hansel und Gretel", and "Der Vetter auf Besuch", an opera buffa of sorts, were not particularly successful. There was a dispute between Busch and Kremplsetzer during the staging of "Der Vetter auf Besuch", leading to the removal of Busch's name from the production; the piece was renamed, "Singspiel von Georg Kremplsetzer".
