Ever want to hear Machine Head cover Foo Fighters’ “Everlong?” Well, we can’t say we did either, but that’s one of the songs that the band played during a secret show in London last night (6). Playing as “Ten Ton Hammer” (dead giveaway there, guys), the band did a handful of covers along with their original material. They also covered Metallica’s “Battery,” Pantera’s “Walk” and “Fucking Hostile,” Iron Maiden’s “Hallowed Be Thy Name” and “Number of the Beast,” System of a Down’s “Sad Statue,”  and Poison Idea’s “Alan’s On Fire.”  Check out the System of a Down cover after the jump. [youtube]http://www.youtube.com/watch?v=vYkadx7RVs8[/youtube]
