Hi all...when reading through Don't Forget The Motorcity there are lots of instances where a group or solo artist have been overdubbed...does this mean the original vocals no longer exists as there are a few examples where both or more versions have been released or canned using the same backing track and the original version is saved...im asking as there are a few tracks that are saying overdubbed but I have not heard the original..so does that mean the original vocals were recorded over...hope this makes sense
