And Pink Floyd did rather well after Roger Waters, even if their two post-breakup albums were mediore. Or even earlier when Waters took over the mantle from Syd Barrett when he went cuckoo.
whilst not their best work, i always thought 'a momentary lapse of reason' and 'the division bell' were great albums and far better than the (basically) roger waters only 'the final cut'
pink floyd always effectively had two lead singers though in waters and gilmour, much like the beatles i guess (who you could argue had three or four).
ian curtis of 'joy division' committed suicide and the rest of the band reformed and became 'new order' and were far more successful (commercially, if not historically) than joy division.
