Marva Whitney - Unwind Yourself

I originally found this single among my dad's collection as a 12 year old, just learning how to use his record player and having no idea what the switch labelled 33-45 was for. I still think the slow version is better - 0.75 speed on the player will get you close enough.
Anyway a couple of years ago I found out DJ Fresh had done the same thing on purpose around the same time, and somehow I never knew.
