People here probably heard about this. These singers are local to me (from Ireland) but its a similar story. At an underfunded school without a music program, a teacher noticed some kids singing around the school. A choir was created despite lack of anyone able to teach the kids. Last Dec. the kids recorded a video of them singing song from "A Star Is Born". They only had one rehearsal (the story goes) before recording and many were shocked at how good the singers were. Since posting, the video has been seen 40 million times on various media sites. The Facebook bit going around makes a lot out of the boys look of "adoration" for the girl singing with him. In any case, I'm so tired of pop music hype that I really like these regular kids that come out of nowhere.
