American here- I watched this for a full minute before I realized it wasn't a rural church in Kentucky! Very well done!

Wonderful! And I like the brisk tempo.

Wait a minute...the guy with the long hair, is he also a voice coach? I was watching a video earlier with a guy that looks just like him teaching people to sing the vowels of a song first. I'm terrible with faces, but I'd swear that was the same guy.
