What was so great about the 80s was that a traditional blues and R&B song like this could get lumped in with New Wave and still sound good alongside bands like The Cure, Thompson Twins, Psych Furs...
that was the beauty of that time in music...It was such a melting pot of styles and a great deal of it was incredible.
