Van Halen's famous edict that "no brown M&Ms" be served to them backstage was the first indication that rock stars are not like normal people, especially when it comes to food. The "rider"—a legal document that stipulates what a show promoter is required to provide for a band playing in their venue—has a long and colorful history. Most groups say their kooky demands (like banning certain candy colors) are included to make sure the whole document is carefully read, but sometimes the intention is difficult to determine.
