Disco music in the '70s was just a call to go wild and party and dance with no thought or conscience or regard for tomorrow.
Disco's are tricky. You look a total wally if you dance too early but after one crucial song tips the disco over, you look a sad saddo if you don't.
Disco will never be over. It will always live in our minds and hearts. Something like this that was this big and this important will never die.
