A rather simple one. How can disco not die at the tail end of the 70's/early 80's and suffer the backlash it did? And what effect would the causes of a living disco and a living disco in and of itself have on culture and musical culture?
Actually...I think Jab and Infernus did pretty good. I'll go with those two. Then you'd have Disco just naturally sort of turning into techno in the mid to late '80s.
I know I didn't issue the challenge, but as an innocent bystander, I'm handing you both the win.
One side effect is there is no Golden Age of stand-up comedy in the United States in 1979-1985 which came about partly because there were so many bust disco owners who just turned them into comedy clubs on the cheap, the underground comics the likes of Kinison and Hicks will have a tougher time getting known in a world of extended Disco.
