From Facebook: At last night's concert, we witnessed something absolutely beautiful. Keep In mind this was a rock concert (Three Days Grace in Edmonton). We saw this girl and a man who seemed to require a lot of dancing room, irritating at first until we realized what was happening. Her father is deaf, she was signing the lyrics to him. We couldn't care less about what was happening on stage, watching them was absolutely mesmerizing. They were both very sweet and her father was very proud of his daughter. So here's one of the songs, sorry just a crappy snippet of what happened.
