Imagine Ian Curtis had no epilepsy, medication, personal issues and lived. However he just quits Joy Division and is replaced with whipersnapper Bono from lesser known Irish outfit U2 who fold shortly after. Bernard Sumner quits after difficult third album "Boy Movement". Pounding electronic stadium disco oddity "Brown Monday" is the final straw for Hooky and he quits before the shambolic infamous Live Aid show.
Joy Division left a perfect legacy. It could have all been so different!
