In "Lady and the Champ" Jake LaMotta relates, in ribald detail, his years as a boxer, and, later on, post-retirement, his many years owning bars, working as a stand-up, and racking up a long list of wives. He developed the show with Baker, to whom he affectionately refers as his future seventh wife, "lucky #7." The former world middleweight champion, whose career in and out of the ring dating back to the FDR presidency has been the stuff of legend, was famously portrayed by Robert DeNiro in the 1980 film "Raging Bull," which earned the actor a hard-fought Academy Award. Curiously, LaMotta is currently being sued by MGM, the studio that made the film, to prevent a sequel based on LaMotta's 1986 memoir "Raging Bull II" from being made. LaMotta, who was born in 1922, turns 90 on July 10.
