I though Kinky Friedman was a marginal country singer, and now I find out that he is a novelist. Look for Don Imus to start hawking his books since they seem to be connected at the hip.
He was far from marginal. He was just...strange. He was a major influence on tons of major musicians.
And, come on, you aren't exactly mainstream with a name like "Kinky Friedman and the Texas Jewboys" (most of whom, ironically, were not Jewish :D)
His songs were generally biting satire. Like "Get Your Biscuits in the Over, and Your Buns in the Bed" (directed at feminists), "The Ballad of Charles Whitman" (aimed at those who try to explain psychos), "G-d Bless John Wayne", Sold American and a few others are all awesome. "L.A. Men's Room" is also good.
