Yep forgot about that and pretty much I hate disco generally speaking but they made that song so much fun. In my opinion only them, Barry White and Donna Summers made disco music palpable in that era
A few years back while I was teaching at a Catholic middle school, when I got tired of the lesson and the students were zoning out I moved all the desks around the wall and put that along video on my laptop and we all danced around in the middle of the room. Never got caught by the principal or complaints fro parents. A few years later one of the students brought me a vinyl album of them.
