 He did however get to sing two more sizable roles, Valentin in Charles Gounod's "Faust" and Silvio in Ruggero Leoncavallo's "Pagliacci".Feeling he was being pigeon holed into the comprimario repertoire at the Met, Cassel left the company after the close of the 1944-1945 season to pursue other artistic interests.He returned to Broadway in 1946 to portray Pierre Birabeau in the revival of Sigmund Romberg's "The Desert Song".
