"Not to be missed is 'O' Sole Mio, in which Hertzog & Ellis delivered a funny duel for the highest, longest and most beautiful tones."
"The Australian John Ellis, with his bravorous voluminous voice. In the end, it came to the realisation that a heldentenor like Ellis and a lyric tenor like Hertzog both have their merits and got the most applause together."
"The referee was the audience with whistles, clapping and hooting. There it finally had its radiant tenors."
