Armless Chinese pianist strikes an overwhelming chord

Liu Wei, a 23 years old armless pianist who lost his arms due to an electric accident when he was 10, performed on a "China's Got Talent Show".

His inspirational heart wrenching performance shows he overcame both physical and emotional handicaps  with extremely hard work, over stepping cramping and abrasion problems as he went to strike a perfect chord.

Although a powerfully enlightening story, upon closely watching and listening to the video several times I wondered if the makers of the show censored the original recording, or is this saying something about the quality of the video ?
