You know, I never heard this version either and the way David sang it totally blew me away. I think he has all that it takes to make it in the music industry, he has the mannerisms, he has the ability and talent, he has the drive and he has the knowledge of what can touch the fans.  The way he sang this song, as with all the other songs, are just phenomenal.  To boot, he doesn't seem arrogant or "into" himself thinking he's better than anyone else. He's very humble
