The ugly fact is that the Missals (of all stripes) were thrown out and of no use to anyone in the pews back then. We went to Leaftlet Missalettes. One could not use one’s Missal…It was far easier to use the Leaflet Missalettes.
Each week (or so it seemed) there was an announcement from the pulpit, next week we will no longer chant the Kyrie, we will recite it in English. Next week, we will no longer chant the Gloria, we will recite it in English…And as most of us know who experienced it, the English translations didn’t settle down until the mid-70s at the earliest with tweaks lasting well into the 80s.
