"If You Leave Me Now" was also Chicago's biggest hit worldwide, topping the charts in other countries such as Australia. It won Grammy Awards for Best Arrangement Accompanying Vocalist(s) and Best Pop Vocal Performance by a Duo, Group or Chorus. In addition, by August 1978 it had sold 1.4 million copies in the United States alone.
The song had been featured in some several television series and movies such as Three Kings, Shaun of the Dead, A Lot Like Love, Sex and the City and the video game Grand Theft Auto V.

Chicago XXXVI: Now, sometimes stylized as "NOW" Chicago XXXVI, is the twenty-third studio album, and thirty-sixth overall by Chicago. It was written and recorded in 2013-2014, and was released on July 4, 2014. Aside from the sprinkling of new tracks found in the band's many compilation and cover albums, Now is the band's next full album of new compositions in the eight years since 2006's Chicago XXX, and it is the next release of original material following 2008's fifteen-year-delayed Chicago XXXII: Stone of Sisyphus. This album marks the first original Chicago credits for veteran musicians Walfredo Reyes, Jr. and Lou Pardini, since joining the band.

Chicago VI is the fifth studio album by American rock band Chicago and was released in 1973. Following the streamlined character of Chicago V, this successor would see the group follow more of a pop music approach, relying less on their trademark horns and exploring varied music forms.

“Jail” is extremely solid from beginning to end where every song has killer chords and hooks which make them standout. There is absolutely no filler material on this disc. While some songs are obviously better than others, there is not what I would consider a weak track to be found. Some are based on a very hard-rockin’, infectious guitar hook. Others revolve around a big sing-along chorus. The rest fall somewhere in between with a combination of the two. I think it is a safe bet that you’ll find yourself singing “Scream” or “Bloodstained Highway” long after the disc has stopped.
