name='Wicked Lady']Most bands shuffle around at some point whether it's because a member dies, they drift apart or the personalities can't (or won't) work together. Sometimes it's a blip (a la Pete Best) and sometimes it's catastrophic to the band (like Bon Scott or Freddie Mercury). Some can find a replacement and prosper and some don't.
Some who have carried on and prospered would be AC/DC
(although I bet Brian Johnson is heartily sick of hearing 'Bon was better' after nearly 30 years), Van Halen
(Diamond Dave was
better) , Genesis
, Moody Blues
and Pink Floyd
(see discussion elsewhere), Faith No More
, Guns and Roses
(although 'prospered' is debatable for the latter), INXS
(ditto).....oh, I could go on but I need a cup of tea.....
Some carry on and it's horrible...almost macabre....
