five full octaves below high C. This means that he could sing near the
limits of human hearing.
Appeared in all of the MacDonald-Eddy musicals. Was the voice of God in
DeMille's "The Ten Commandments" according to his published obituary.
Uncredited - Delos provided the voice for God on Mt. Sinai. (But not for the burning bush scene which Charlton Heston dubbed.).
