“Such a wonderful tale. Pongrác Kacsóh followed in the tracks of the poet without wiping off the butterfly wing scale with rough hands; his fantastic, gorgeous music is distinctly different from any operetta we have heard before with its Hungarian motives and genuine folk style”, reports on the 1904 premier of John the Valiant the newspaper called Újság. It might sound incredible, but the title role was played by the great prima donna Sári Fedák. “When I had sung ‘A single rose says it better’, the fate of the work was sealed. Everyone was crying in the audience, and I cried with them.” There was hardly a season since its opera house premier in 1931 when it was not included in the programme. With John the Valiant, the OPERA wishes to honour the 200th anniversary of Sándor Petőfi’s birth in 2023.
