When you’re playing “Amazing Grace,” regardless of where it is in Mass* or how much time you actually have, you will play all five (or however many you have) verses. Because there are very few hymns that everyone knows, and this is one of them. Although when I did this recently as a recessional hymn, I made sure the cantor announced we were doing all five, to ensure the priest saying the Mass didn’t take off. And oh, did everyone sing all five verses, loudly and majestically. Now, as a reward for reading that, here’s Elvis Presley singing “Amazing Grace” with the verses in a different order than I’m used to.
* I don’t subscribe to the idea that “Amazing Grace” isn’t suitable for Mass, thank you.
