I was thinking about putting together a group of four (two male two female) to do oldies but goodies type of music. I am thinking about the 50+ crowd as a target. Probably would consist of a kb and guitar over midi files maybe some mp3's. The emphasis would be on vocals and harmony vocal stuff. I have heard a few a capella groups doing doo wop stuff. Some of them pretty good, but I still think a little accompaniement would make it better. My questions are: Has this been done to death? Would there be any market for this stuff? Would there be enough money to pay four band members? What venues would be interested it this stuff? Any thoughts?
