Peter Hofmann

Hofmann's busy and demanding schedule in combination with an "imperfect vocal technique", led to intermittent vocal problems which became more prominent in the singer's opera performances in the late 1980s. These difficulties led him to completely abandon his opera career in 1989 in favor of pursuing a full-time career in popular music. Hofmann had already spent portions of his opera career performing and recording popular music, and he had already achieved success with tours and recordings of classic rock during the mid to late 1980s. He continued to perform pop and rock songs until his retirement from performance for health reasons in 1999. He had been diagnosed with Parkinson's disease in 1994. Provided by Wikipedia
