My two favorite Jack's of all time (that tells you a lot coming from a person who has a brother named Jack) came together to make this simple but amazing diddle that will forever be stuck in your head.

What we have here is thoroughly Tenacious D. Black roars at his longtime bandmate Kyle Gass, aka Kage, to “just play the best shit you ever fuckin’ played,” and explains the stakes, “Jack White invited us to party.” After a serviceable acoustic solo, Black sings, “You blew it, Kage / You played the worst shit you ever fuckin’ played.”
