What I find interesting is that growing up (I was born in 1951) the Fatima Prayer was not said as part of the Rosary where I lived, neither at home, nor in my parochial school, nor when attending a Rosary at a funeral home chapel. Back in the 1980's when dairy farm work often precluded attending Sunday Mass I would go to a daily Mass on my next day off. There would sometimes be a public recitation of the Rosary before Mass and that was my first recollection of hearing the Fatima Prayer. I thought for a long time that it was something Pope John Paul II had introduced, and no, I wasn't happy about the change.
