I'd never heard this song before that performance but he was amazing and made me really like the song. Then I heard the original on the oldies station and totally loved it even more.
He had a very serious illness for almost a year right after the Idol season/tour so that delay kind of took him out of the public eye at exactly the wrong time.
@angelablk1 Bo better than Carrie? Nigel Lythgoe, an executive producer of the show, said earlier this year that revealing all the vote totals would, in some years, rob the series of its suspense. In the fourth season, he explained, Carrie Underwood so dominated the voting, winning every week by a large margin, that disclosing the totals would have diminished viewership. - nytimes.com/2008/05/24/arts/television/24idol.html?_r=3&oref=slogin
Bo was much much better than Carrie, but, trough competition, audience favored country singers, like Scott or Carrie. Carries rendition of "If you don't know me by now" was awful. Audience voted for typical American Sweetheart.
