Gary. Your right on. A good friend who worked in a band with me years back was a dept. manager at a new GC. Made peanuts and worked his tail off.
As for the students if they would look at their"musical heros" they would see a common thread of time spent "wood shedding" to reach a high level on their instrument. But then again the rock star, who can sing/scream really high with no training gets all the attention and $$$. Go figure.
