OK here ya go:
My heart bursts with joy and anticipation when I hear this, knowing that I am about to assist at the most beautiful thing this side of heaven.
Here is a video of the Saint Philip's Boys Choir singing Panis Angelicus. Ignore the floating heads, it was big at that time, you'll be able to see the real beauty. Oh, and ignore the faulty translation.
Thank you for posting! That was amazing to hear. Truly sacred.
