This show had me laughing pretty much from start to finish, except when I wanted to cry, like when Mariah Carey sang Def Leppard (And I'm not even a fan of Def Leppard, it just was terrible to hear Mariah Carey destroy the song), and of course when Celine Dion sang AC/DC - I ran to the bathroom and vomited at that point.
The one least metal moment that they missed ... was when kid rock destroyed Bad Company's classic - then again, maybe Bad Company isn't really considered metal.
PS: The chicken dance maybe wasn't so bad, it was funny, but it certainly wasn't metal. I think that Celine's transgression against metal should have been #1.
The whole programme probably had nothing to do with metal in the first place.
