The Van De Steen Chorale, who were featured during the televised Christmas midnight TLM, are alumni members of the Manila Cathedral Boy's choir who sang and chanted for the TLM at the cathedral forty years ago. The Manila Cathedral Boy's Choir was founded by the late Rufino Cardinal Santos and trained under Father John Van De Steen, CICM, a Belgian missionary. Now in their late 50's, their cherished dream to sing as a group Sacred Music and the Gregorian Chants was fulfilled when they were invited to sing as a choir for the inaugural Traditional Latin Mass at St. Jerome Emiliani and Sta. Susanna Parish last June 29, 2008.
