This is from another version of that show in 2011, Korea's Got Talent. And I think it is every bit as powerful and moving as the others. Some parts, even more so. It's a young kid whose named is bizarrely appropriate, Sung-Bong Choi. The video has been seen by 78 YouTube viewers. So, it's possibly you're one of them. The impact of the video isn't just the singing, but the story and audience reaction. In fact, the moment at around the 3:15 mark is one of my all-time favorites.
Two updates. He finished second in the competition. And in 2012, he sang the national anthem to Korea's athletes before the London Olympics. I shall say no more.
Except that the video starts after a short ad, which you can click past in a few seconds.
