Rudolf Lutz, organ artist, compositian and conductor from Switzerland, gave the pleasure for the Sisters of St. Charles to play a special organ concert for them and for the guests: On the small organ instrument in the house chapel Regina Angelorum he intoned the favourite spiritual organ chants of the Sisters' convent. He introduced every chant with a musical and spiritual information, so the listeners had a special experience and the whole concert became a prayer: everything to the greater glory of God and to the joy of the listeners.
