Things will be fine for all of us... It's the wait that seems to be the tough part.
Have you come up with anyone else in or for the band that can sing if your ex-singer doesn't want to stop back for a CD or two? On a few of the songs from the last album, I think having a deeper voice thrown in once in a while as back up would have been cool... even a bad voice kinda talking in a few parts would have finished off the songs. ((Like I am ANY kind of music expert! I can't even carry the tune for "row row row your boat" or "happy birthday" successfully))
