Back in the day it seemed to me that performers got to the top by working constantly. Most had hundreds of hours of stage experience and likely big repertoires. They didn't have the benefit of doing 12 shows a year and just being a star. At some point that changed to a "get discovered" type system and in my opinion you end up with less well rounded talent. I guess my question would be when did that start? Was that purely a 50's forward symptom of the rock and pop explosion or did happen earlier and I'm just not aware of it?
