In attendance was the Archduke of Austria, His Royal Highness Georg Habsburg-Lothringen.
The Schola Cantorum, directed by Fr. Cyprian Constantine, OSB, chanted the daily propers set forth by the Graduale Romanum.
This sacred liturgy was celebrated in accord with the reforms of the Second Vatican Council, "SACROSANCTUM CONCILIUM," which was solemnly promulgated by his Holiness Pope Paul VI, 1963.
