Many, and I do mean Many, years ago Jack Jackson used to play this on his radio show. He was a trailblazer of a DJ who used technical tricks such as multi-tracking,etc, very innovative for that time and not to every listeners satisfaction. 'I wish he'd stop messing about with the records' was the jist of many complaints. But he carried on and blazed a path many would follow. He also chose all his own records, and scoured widely for them. I was an avid fan, and listening one night heard him play this wild music, harmonica and eerie whooping voice. When it was done he introduced it as 'Hootin' Blues' by the Sonny Terry Trio'. He played it freqently. It was much requested. Later, when I got into folk music and learned of Sonny Terry the memory of that Jack Jackson show came to me. Yes, Jackson definitely called it 'Hootin'Blues' by the Sonny Terry Trio. Very probably Sonny, Brownie McGhee, and his brother 'Sticks' McGhee. Burl.
