Now you have!
I believe the quintessential disco song was “Staying Alive” or “You Should Be Dancing” by the Bee Gees. As much as I disliked disco, both tunes had an irresistible groove. I’m a drummer and the drums were boring, but the tempo was just perfect for toe-tapping.
Just watched the YouTube of Let’s All Chant. Other than some keyboard, it is exactly the kind of disco I disliked. I had to take my earphones of with all its repetitious crap. Oy,Oy, please. I don’t get the enthusiasm since it sounds like almost every other disco.
