Heard him at couple of times at a bar (Guarranteed Wholesome Dance Hall & Saloon) I once co-owned in Huntsville, TX back in '73-'76.
He'd practice with his band in shorts and t-shirt which exposed all his tattoos, most all looked self inflicted.
We booked Asleep At The Wheel, Waylon Jennings, Willy Nelson, Jerry Jeff Walker to name a few.
