Mr. Anderson started as a performer. He studied at the Curtis Institute and was planning a career in opera. After performing for some years, he was employed as a stage manager for the original production of Camelot. Because he had a background as a singer, pianist and conductor of small orchestral groups, he had sometimes assisted the show’s musical director and conductor, Franz Allers, in various musical chores. Allers flew to Chicago during the run to conduct a Gilbert and Sullivan program in Grant Park on a Sunday. He was expected to return in time to conduct the Monday night performance, but rain caused delays and finally his plane was forced to land in Philadelphia instead of New York. The assistant conductor, Max Tarr, was on vacation. Mr. Anderson volunteered to conduct the performance and did well. He went on to work widely as a musical director and conductor. He later returned to performing at least once: in Philemon at North Shore in 1975.
