Being asked to leave a band for any reason sucks big time and is a major blow to one's ego.Happened to me once some decades ago,the singer said to me " we're splitting up for a while and doing our own thing".Ok.What he failed to tell me that was his own thing was to carry on with the rest of the band ( who,it turned out,wondered why I left..) with his new mate on bass.Shortly after that,the new band chucked HIM out...20 years later I'm in a reasonably succesful band with the guitarist from that band,and the previous singer has cleaned himself up from the nasty drugs he was taking that we didn't know about.
