(AP) — A pipe organ that has served as the musical backdrop to an amusement park clown is now the subject of a civil court case. The Wichita Eagle (http://bit.ly/1Qa3RRH ) reports an attorney for Joyland Amusement Park owner Margaret Nelson Spear filed a civil breach-of-contract lawsuit Wednesday in Sedgwick County District Court. The lawsuit claims that ex-Joyland employee Damian Mayes didn't pay money he owes after agreeing to purchase the Wurlitzer Style 160 "Mammoth" Military Band organ about six years ago.
