I wrote once that college bands are mostly made up of college students who are not majoring in music. Two of my nephews had successful bands in college though neither of them studied much music. It was a somewhat profitable hobby. The herd inevitably thins. Most of the boom time band wagon jumpers give it up after high school or college.
Some guys do get into it to attract women.
I have seen some promising players who landed some hot babes who saw them play. You don't need to be going out at night and playing in those bars where all those women are. They are jealous of what attracted them in the first place. Hey, my axe isn't jealous of you. They live at home and have their own studios and the folks pay all the bills.
