Thanks for all of your responses; I pretty much agree with everything that has been mentioned. We will have a band meeting after our upcoming gig later this week. I suspect it will be short and there will be mostly "no way is he coming back" responses. One of the results of what he did is that we now know we can succeed without him, and I doubt that any of our current members are willing to allow that situation to happen again.
As for finding another lead singer; we probably will not make a serious effort to do that right now. We all sing lead on some songs during a typical set, and I have taken on the largest share of that duty. In the bigger picture, I have gained more confidence in my singing because of the situation. I was already doing about twenty percent of the lead singing in the original group, so I have been able to increase that percentage by careful song selection. I won't be getting any Grammy awards, but I do get compliments on my singing, so I suspect we will just continue with this new arrangement for now. One of the things we have all learned over the years is to "play to each members strength musically", while keeping it as simple as possible. This is pretty much an "oldies" band that plays 50's, 60's, and 70's music across multiple genre's. We have added more country and 70's R&R to our songlist because those are my stronger areas.
With regard to the possibility of playing again with our former BL; in the past, three of us (two of us who are now in the new band) played a few dates that were built around our harmony singing. Our former BL is a baritone, one member sings bass, and I am a tenor. So the harmonies just kind of came together. At the time there was talk of booking more gigs around that format. I would consider doing that with the understanding that it would be strictly a side gig that would not interfere with our new band. And it would go with knowing that the former BL cannot be fully trusted again.
So thank you again for your comments and keep them coming if you like. And I will report back after our band meeting.
Thump on,
