I love his performance, but the part that really gets me is his incredibly humble attitude and the audience's reaction. (Is the judge in the middle fighting tears in a few spots?)
As an FYI he did win the whole thing. And the competition was GOOD.
There's a much better quality clip on youtube... and I actually went out and found his debut album (One Chance - Paul Potts) at BestBuy. Excellent performance but the recording is a big disappointment, very harsh sounding, audibly dirty on loud passages. Basically, recorded too hot with a hard limiter... really a shame, the guy has such a great voice. Still, glad I picked up the CD.
