re: #107 Sea Mexican!

Van Halen, IIRC. However, there was a solid logic behind it: producers willing to cut corners with the M&Ms were more likely to cut corners elsewhere. Again, IIRC, they cancelled at least one show because the first alert was the brown M&Ms, and upon further inspection, they discovered that there were several security hazards.

It indicated to the band which setup companies actually followed instructions. They could tell who had read the contract if they followed that.
