The Smoking Gun has found Van Halen’s infamous "no brown M&M’s in the band’s dressing room" rider. Why did the band ask for this?:
While the underlined rider entry has often been described as an example of rock excess, the outlandish demand of multimillionaires, the group has said the M&M provision was included to make sure that promoters had actually read its lengthy rider. If brown M&M’s were in the backstage candy bowl, Van Halen surmised that more important aspects of a performance–lighting, staging, security, ticketing–may have been botched by an inattentive promoter.
