well this is more difficult than that... there could be a million different reasons for one leaving the band...for example Finntroll where the singer's voice went bad but they're still very good friends and as soon as he can he'll join the band again. So you just shouldn't judge a band of their membership and that how permanent is it...ah...crappy shit it's just tooooo late
LOL yeah true..... of couse there always is the reason that one of them is a jackass, one of them is a heroine addict, one of them is a fag who trys to fuck every member etc etc......
cou.ld be a nimber of things!
