MUSICIAN and mystery writer Kinky Friedman brought his long-shot bid to become governor of Texas a little closer to reality yesterday when he turned in 169,574 signatures to get on the November ballot - more than 31/2 times the number needed. Friedman, clad in his trademark black cowboy hat and Western clothes, stood on the steps of the Texas secretary of state's office and quipped, "Thank God for bars and dance halls. Every signature counts, whether it came from a country club or homeless shelter."
