In 1972 a new "Calypso" ride was installed, and named simply "The Calypso". In 1975, Bill Barr retired to Italy, and park veteran William "Bill" Robinson took over some of duties left by Barr. Bill's knack for producing interesting promotions enabled the park to enjoy large crowds. Some of the more novel promotions developed by Bill included the 1976 designation as the country's only "Official" Bicentennial Amusement Park, the Coca-Cola/WSAI Radio Rock, Roll n' Remember concerts, and the Jell-O Jump, where contestants jumped into a huge barrel of gelatin to find the winning key to a new car.
