Van Halen got a reputation as being diva's because in their contract they requested that bowl of only green m&m's be in their dressing room. When asked Eddie said it was because their stage equipment had extensive instructions on setting up. One place didn't set it up correctly and it ruined the basketball court it was set up on. So in their contract they had the instructions for the stage set up and then in the middle of it was the request for green m&m's. So when they got to their room if there wasn't a bowl of green m&m's they could assume the stage wasn't set up correctly either.
