Many years ago, I was co-leading a 8-piece horn band. We hired a lead singer, who was VASTLY more talented vocally then the other singer and I. I greatly resented the fact that he took over half of the songs that I used to sing, even though he brought the group to an entirely different level. Better sound, better crowds, and a lot more interest in the band was the result of his involvement. He was only with us a couple of months when he was tragically killed in a automobile accident by a drunk driver. His passing effectively killed our band, and I felt like a total jerk for feeling the way that I had felt about him. We "soldiered" on for several more months before disbanding - none of us could get past the thought of him, and how he made us sound. I would suggest that you might think about the possibility that YOU are the problem. Like suggested in a previous post - lay back, and enjoy the ride. Good vocalists are hard to find - good luck !
