So, we got a six piece band, lead and rythm guitar, drums, keys, singer and a bass (me), and the dude that's singin' is a huge problem. Guy is totally tone deaf, a terrible singer. We would like to kick him out, but the problem is that we're long time friends. I'd like to kick him out, but I'm afraid that action would destroy our frendship. Do you have any advices or the tips? Is there anything I could do to improve his singing?
