This undated photo provided by the Tulsa Regional Chamber shows Cain's Ballroom, built in 1924 and known as the regular performing venue of Bob Willis, the "King of Western Swing." The club now draws a steady stream of big acts across all genres but it's one of a number of buildings in Tulsa that date to an oil boom in the 1920s. (AP Photo/Tulsa Regional Chamber, Don Sibley)
