Yes, glad you clarified that. My original assumptions and gut feeling were, it seems, correct, but my laziness in failing to research it in detail led me to just believe the accuracy of the article as written. I have always classed it as what would now be called a 'crossover' record... it certainly sounds like one.
An interesting aside about a great singer - songwriter. Anything that keeps him and his music topical is fine with me. May he be remembered forever. For sure his music will keep us soulies dancing for many, many years to come.
