Some have questioned these biographical details behind Greenwood's declarations, but I won't. He's a singer/songwriter, and not necessarily the guy he's singing about. Greenwood wasn't necessarily a volunteer soldier or an ideal husband. Johnny Cash didn't necessarily shoot a man in Reno.
My former co-worker Jack Neely takes on Lee Greenwood's horrid ditty about the U.S.A. Essays like this make me thrilled that I do know Jack. It's a shame, however, that Greenwood (and his supporters) will probably miss both the point and the references.
