You hire Billy Joel to play at your party. You buy a grand piano and a electric piano for him. But he don't know your requests for Julian Cope and the Os Mutantes. You have a good time but next time you'll hire a professional dammit. The party is blown away by Joel. Billy gets wasted, tells jokes. He gets more attention then you do. But that's o k. You still sleep with a couple super models that night while Joel only snaps one.
