Joe, I don't know if he ever recorded it, and it's certainly not on his recordings that I have. I was a member of his club for a couple of years, and I remember his singing it and his introduction that a friend of his brought it back to England. And that the friend mispronounced the name as 'Hewston,' so the friend possibly had it from a written source. It had the 'Long Time Ago-O-O' chorus and the 'Houston, Sam Houston' interjection
Most earlier Tawney recordings mostly comprised traditional songs he had personally collected, and songs that he had written.
