In September 1980, the band released its second collaborative album with Deodato, "Celebrate!". It became a bigger commercial success than "Ladies' Night"; the lead single "Celebration" remains the band's only single to reach No. 1 on the "Billboard" Hot 100 singles chart. The song originated from the lyric "Come on, let's all celebrate" from "Ladies' Night" which inspired Robert Bell to write a song that he described as "an international anthem." The band developed the song on a tour bus after attending the American Music Awards. The song was used in national media coverage for the 1980 World Series, the 1981 Super Bowl, the 1981 NBA Finals, and the 1981 return of the Iran hostages.
