Thanks for the upload. I remember seeing this as a kid and it's funny how memory plays tricks because I seem to remember him dedicating the tune to John Lennon, not the delightful Yootha.
I wish I could have had the chance to see Billy in the early days when he was in the humblebums with Tam Harvey. I've got their LP on the transatlantic label from the late 60,if you get a chance check it out for me it one of my favourite records.
