U.S.—Sources at your church confirmed Sunday that the worship leader helpfully shouted out the next lyric to the song you were singing, just in case you couldn't read it on the giant projector screen behind him.
Just before each new stanza started, the worship leader decided to help everyone out by yelling out the well-known line that was projected in a massive font for everyone to see. He did this every time a chorus, verse, or bridge began, always being sure to feed you the next line a measure in advance so you'd be prepared, and also just in case you couldn't see it in foot-tall letters behind him.
"Alright, church, let's sing it again!" he then cried out as the first repetition of the bridge ended, even though the worship lyric slide behind him pretty clearly said "REPEAT" in giant letters, sources confirmed.
At publishing time, witnesses claim the entire congregation came up to the worship leader after the service and thanked him for his selfless act of heroism to make sure that everyone could sing along.
