I saw the youtube video of him doing it live when he won, it was horrible. He was offkey most of the song, screwed up harmonies, etc.
At least Solinger can pull off the country thing sounding decent and with class. Bach just ain't country.
And for the record, beyond a bit of J. Cash, I don't like country. But I've heard enough of it second hand to know what works and what doesn't with the genre, and Bach definitely doesn't work.
