The band's first mainstream success came with the release of their fourth album Wild and Peaceful (1973); it contained the US top-ten singles "Jungle Boogie" and "Hollywood Swinging". The band entered a period of decline before they reached a second commercial peak between 1979 and 1986 following their partnership with Brazilian musician and producer Eumir Deodato and the addition of singer James "J.T." Taylor to the line-up. Their most successful albums of the time include Ladies' Night (1979), Celebrate! (1980) and Emergency (1984), the latter being their highest-selling album, with two million copies sold in the US. Their hit singles during the period include "Ladies' Night" (1979), the US No. 1 "Celebration" (1980), "Get Down on It" (1981), "Joanna" (1983), "Misled" (1984) and "Cherish" (1985). The group has continued to perform worldwide, including as a supporting act for Van Halen in 2012 and their fiftieth-anniversary tour in 2014.
