Buried amongst dozens of points in Van Halen’s rider was an odd stipulation that there were to be no brown M&M’s candies in the backstage area. If any brown M&M’s were found backstage, the band could cancel the entire concert at the full expense of the promoter. That meant that because of a single candy, a promoter could lose millions…
To ensure the promoter had read every single word in the contract, the band created the “no brown M&M’s” clause. It was a canary in a coalmine to indicate that the promoter may have not paid attention to other more important parts of the rider, and that there could be other bigger problems at hand.
Whenever the band found brown M&M’s candies backstage, they immediately did a complete line check, inspecting every aspect of the sound, lighting and stage setup to make sure it was perfect. David Lee Roth would also trash the band’s dressing room to prove a point — reinforcing his reputation in the process.
Van Halen created a seemingly silly clause to make sure that every little detail was taken care of. It was important, both for the experience of the fans and the safety of the band, to make sure that no little problems created bigger issues.
