So, the only person I liked looking at while they were singing is the young lady in the yellow. Second, was the young lady in white.
Other than that, ESPECIALLY IN THE AGE OF YOUTUBE, folks really need to work on facial expression. I mean it took dude in the green until the vamp to look like he cared he was singing.
Body language is as important as vocal ability. One needs to look like they enjoy the lyrics he or she is singing.
I've never heard the song before. It's nice, though. The group sings well.
