Look, I don't care about Mariah Carey, but she was clearly ripped at tech support or someone for screwing the whole thing up. She says the monitors aren't working, and that it isn't the same song from "mic check".
I think it would be pretty hard to perform in front of thousands of screaming people if someone switches playbooks without telling you.
Also nice Egg, TOSU (don't want to offend Oklahoma state fighting mullets)
