Kate and I went to see Walk the Line tonight. Juaquin Phoenix and Reese Witherspoon sang all the words to tons of great Cash songs and duets. I especially liked Dylan’s “It ain’t me babe” and the scenes at Folsom Prison. Very well done.

But I was wondering, in the middle of Folsom Prison, during the guitar solo, Johnny Cash says “soo-wee”, like he’s calling a pig, I think. Am I right about that? If so, what does it mean? And what is the origin, or spelling, of “sooo-weee”? Is it “sow eat?”
