Interesting thread, Art.

Country blues is full of Non PC lyrics. Sugarbabe It's All Over Now by Mance Lipscomb ("Going dowtown gonna get me a rope, Whup that woman 'til she buzzard lope" and Bo Carter's Soo Cow (Soo Cow better come home quick, I'll break your leg with a stick.") come to mind and the one by Blind Boy Fuller where he brags about shooting his woman which he actually did according to some sources.

Then of course there is Lightfoot's "For Loving Me".
