Ok so my band started out as a 6 piece we formed just to play a talent show a couple years back and ended up becoming a real band. About a month after our first real show our lead vocalist left with only 3 weeks before another one so our guitarist took over singing. It was supposed to be only until we could find a real singer, well I guess he liked the attention and decided to become singer. Problem is, he's not very good. People like our music but we've always been told to find a new singer, and whenever the guys bring it up, he pitches a fit. Do you guys have any advice on how to handle it? He's an excellent guitarist and we want him to stay in the band, just not as a singer.
