Myself and our lead singer had been in a band together since high school, as well as best friends. We fancied ourselves to be a Lennon/McCartney combo (although not nearly as talented, of course!) Our band lineup solidified in 2001 and remained steady for about 6 years, when we added a rhythm guitarist/backup singer. The main reason for adding him was so that our singer could be more of a frontman without being confined to the guitar/mic stand the whole time, and he was a really good harmony singer. He eventually started bringing in his originals, which was fine with us, except he insisted on singing them too. Egos started to get ruffled.
Then he and the drummer developed a pact with one another, and they wanted to focus more on this guy's originals, and kick the singer out totally. We practiced at the drummers house, so it was up to him to tell us when we could come over. I'd arrive to practice to find that they didn't tell the singer, and we'd just end up working on the new guy's songs. They would tell me to not tell the singer of these "secret practices", and I didn't tell him because I didn't want to start anymore drama.
Then one day they laid it down for me: The singer was done, out, finished. As for myself, either I play the songs THEY want to play, or I'm out too. I went along with that for about 2 gigs before I said "F" this and quit. The new guy's songs weren't very good, nor was he as a lead singer, and the covers they chose weren't good ones, and the 2 gigs we did play were terrible. It's sad, because we were all such good friends, and the band enhanced our friendships all the more. But, all good things must come to an end, I guess. I hardly play anymore, just because of the negative feelings I associate it with.
PS- those guys never replaced me, and just sit around each other's bedrooms recording songs on garage band... lame
