Bass David Leigh, center, appears with Daniel Schmutzhard, right, and Lauren Fagen in Wagner's "Götterdämmerung" at the Zurich Opera on Oct. 31, 2023. Leigh, an operatic bass, is the son of Mitch Leigh, who wrote the score for the musical “Man of La Mancha." This month he’ll take on a major role as the jailer Rocco in a new production of Beethoven’s only opera, “Fidelio,” at the Washington National Opera, opening Friday. (Monika Rittershaus via AP)
