Pentecost Missa Cantata at Lourdes

Yesterday, he celebrated a Missa Cantata in the Immaculate Conception Basilica and has posted some photos taken by a young father who was present with his wife and children.
See several posts at TLM Lourdes for 11 May. Father makes the pertinent comment:
If I remember correctly, we had pilgrims from England, Ireland, Germany and USA. The language for the Mass was no problem, since everyone wants Latin! Isn’t that innovative in a place where, including all the pilgrims, there may be well over one hundred languages present?
