Woody Guthrie, Philip Pullman and Larry Grayson may seem like strange bedfellows, but all three had/have a common obsession.
Guthrie recorded several songs about DUST. Indeed, he became known as the "Dust Bowl Troubadour".
DUST is a major theme in Pullman's trilogy His Dark Materials. Indeed, his novel entitled The Book Of Dust is due to be published in 2009.
Grayson's stage act included running his finger along the top of the back of a chair, searching for DUST, then exclaiming, "Oooh! Look at the muck in 'ere!"
