The Beatles are probably the first band to use contract riders to gain a few backstage accommodations for the artists themselves, such as clean towels, a few Cokes and a television in their dressing room. As concert crowds grew, so did the amounts of money involved, and before long, superstars used their clout to demand ever-expanding lists of amenities. But the most infamous rider of all is Van Halen's demand that there be a bowl of M&Ms backstage with all of the brown ones removed. The story is that the band would go ape at the mere sight of a brown M&M, giving cause to cancel the gig and trash the dressing room. In reality, though, the rider was a cagey bit of risk management.
