According to Google, this was an original Dolly song for the transgender movie "TransAmerica". It was nominated for an Academy Award (of course).
Just an FYI about Jason Castro from someone who does not know him, but who does live in the Dallas area where he grew up —
Here are some (mostly YouTube links) from local sources.
A Dallas TV spot from several weeks ago, with pictures before the dreads, in which he’s described as an athlete and “merit scholar”:

From the student newspaper at Texas A&M (which, by the way, is one of, and perhaps the most, conservative public universities in the nation):

An on-campus interview done pre-Idol:

And a pre-Idol video of him playing at (conservative and evangelical) Lake Pointe Church in Rockwall, his home congregation.

Perhaps the perception of Castro as a dumbed-down pothead should be reconsidered.
Yep, I couldn’t even find a youtube version that waasn’t from the transgendered movie. I can’t even listen to the song withoput seeing those images now. :/
