Hey! I taught this guy on my mission in the tiny town of Laprida, Argentina! (the singer of the band in the youtube video) He would always play guitar when we'd teach him and his family. Apparently he kept it up and he's doing really well in Argentina now.
Here's a picture from a long time ago of us with him (he's the one with the guitar)
He never got baptized, but his mom and dad did. What a blessing that email exists to keep in touch with people so far away.
