It seems that, more often than not, when my wife and I go to a show or watch one on TV the bass player is sporting some sort of little hat. Sometimes it's a beret, sometimes it's a pork pie or some undersized fedora. Now I can understand that there's some follically challenged folks out there, but... In any case, my wife has made it clear that if I ever show up on stage with some "stupid little hat" on my head it's all over. So what's with the hats?
