In 1990 the consultants who drew up the conservation plan for the former hospital site found the chapel to be of significance to the whole State of New South Wales, saying that it:
Since 1993 the chapel has been regularly used for the celebration, with official permission, of the traditional Latin Mass. These Masses are usually sung, using Gregorian chant, which had been described by the Second Vatican Council as 'distinctive of the Roman liturgy; therefore, other things being equal, it should be given pride of place in liturgical services'. The chant's importance to the musical heritage and to the living culture of the West has been increasingly acknowledged in recent years, even in secular circles.
Mother Xavier, who had many musical friends, including Madame Melba and John McCormack, insisted as always on the highest standards in everything her Sisters did. The nuns at Lewisham became famous for their music as well as their medicine, and released two LP records, which included some Gregorian pieces. No doubt Mother Xavier would be pleased to know that the preservation of the chapel built in tribute to her is linked in a special way to the preservation of the most distinctive form of Catholic music.
