This is a topic that is near and dear to my heart. I wasn't raised in a church that played any of the old hymnns, and I didn't hear most of them until I was about forty years old. I fell in love with these old hymnns, and, now I know hundreds of them. We'll play them for hours at festivals.
      In the Catholic church, we wnent from the latin gobbldygook of the fiftys to the "folk" junk of Vatican II. Mostly uninspiring, uninspired pap.
    My 22 year old son plays organ and piano in several churches, including Catholic and Baptist and Methodist services. He is given a lot of latitude to pick his own music, and he uses a lot of the old Protestant hymnns in the Catholic Church. They love it!!!! All of the other denominations love it too!!! You can see the lights come-on in peoples' eyes, and hear thenm really sing out with the old hymnns. I think, that if people had a choice, they would like the old stuff.
