BEVERLY HILLS, Calif. (AP) – Jack White swears he really did make up “Fly Farm Blues” on the spot during the film “It Might Get Loud.” White says the director told him he was setting up the camera for the next scene and he wanted White to compose. White says a spider walked across his leg, so he sang about a spider, and they were on Fly Farm, and he liked the way that sounded. “It Might Get Loud” is out on DVD today. Jimmy Page and The Edge also appear in it.
