It's not enough that a world-renowned performer felt moved to offer his song for free, just to honor Our Lord? Maybe you should be thankful it wasn't Lady Gaga, in a dress made of Communion hosts.
No chance of Lady Gaga or any well-known performer at my small Tridentine Mass. We’d rather just have an understated hymn by a neighborhood choral singer anyway. No chance of desecration of The Host here either (or a priest standing outside welcoming active homosexuals, etc.).
In our church we’ve had the priest ask for applause for exceptional singing at the end of the mass.
I was raised Congregationalist in New England. We barely spoke to each other on Sundays, let alone applaud. Kind of the ultimate uptight WASPs.
