I mentioned on another thread that I recall reading (30 years ago maybe?) that the leftists had their agenda all planned out and started pushing it through while those bishops without an agenda "were still finding their seats and brushing up their Latin."
BTW, where did people find those "12-minute" Masses? I was in high school when the changes started coming in, but went to a lot of pre-VII daily Masses in jr high; they usually lasted at least half an hour; a 25-minute Mass was considered speedy!
The 12 minute Masses were a particular feature of big urban churches, especially downtown churches where people would come for speedy Masses at noontime. They were sloppily said but they "counted." Another thing that was clearly an abuse was that many people skipped the Mass altogether - they would come flying down the aisle just in time to drop down in front of the altar rail and take Communion, and then they would fly right out again.
What you recall is a book called "The Rhine Flows into the Tiber," by a pseudonym priest, Fr. Xavier Rynne (sp?)
