劇場支配人
In 1961 Gamson left the AOS and moved with his wife to Europe, working actively as an opera conductor in theaters in Italy for two of years. During this time he returned to the US to conduct a 1961 television broadcast of Mozart's "Der Schauspieldirektor" with Eleanor Steber as Madame Warblewell, Jacquelynne Moody as Madame Heartmelt, and John Kuhn in the title role. He also conducted the Voice of Firestone presentation of Verdi's La Traviata on television. The Gamsons moved back to the United States in the mid-1960s, settling in Westchester County, New York. Gamson worked as a conductor with the AOS again in 1967, notably conducting Handel's "Giulio Cesare" with Montserrat Caballé as Cleopatra.
