Hi Jamesy,
DJO is a Chicago label, I believe. Don't know of any other releases on the label. "Tale of Sadness" was released about 1970, and currently sells for £150, when it turns up (don't think I've seen one apart from Nick Brown's copy, which he sold some time ago).
I love the record; and to be completely truthful I thought the chorus said "It's all about boxing, in the seventh round, it's all about boxing now".......then I found out he actually says Foxy & The Seven Hounds!!
