This song actually has nothing to do with the drug or fans of Catherine Wheel. Rob Dickinson gave an interview in 2006 in which he describes "crank" as being British slang for an odd or eccentric person. When he sings "call me crank," he's actually referring to how he views himself and that he's comfortable in acknowledging that he's a bit unusual. Like most of Dickinson's songs, it's representative of his introspective lyricism.
