New evidence of Tolkien's loathing of the changes introduced by Vatican II (the Second Vatican Council)

We already knew that the lifelong-devout Roman Catholic JRR Tolkien was extremely dismayed by the changes introduced by Vatican II; but new anecdotal evidence of the extreme intesity of his reaction was recently published:

But when Tolkien arrived next time at services and seated himself in the middle of a bench, he began to notice other changes than the language, one a diminution of genuflection. His disappointment was such that he rose up and made his way awkwardly to the aisle and there made three very low bows, then stomped out of the church.
