 In his early Munich years Busch 's attempt 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 <unk> und <unk> , a romantic opera in three acts , <unk> und <unk> and Der <unk> <unk> <unk> , an opera <unk> of sorts , were not particularly successful . There was a dispute between Busch and Kremplsetzer during the staging of Der <unk> <unk> <unk> , leading to the removal of Busch 's name from the production ; the piece was renamed <unk> von Georg Kremplsetzer .
