Women are the major cause of the blues. If you got one, she's probably steppin' out on you, and if you had one, she probably left, leavin' you with a long walk to Wichita Falls. People from the South often get the blues, especially if they become displaced. Black folks always got the blues. The fact is, they invented it, mostly while picking cotton.
Cotton picking is enough to give anybody the blues.
Others get it when it don't. Them damn ol' blues just keep hangin' 'round. Bodicus mutilatimus, unemploymi forevercus. Nunc Tutus Exitus Computarus. Litigata Ergo Sum.
