Earth, Wind & Fire hit the road hard after releasing their 1975 breakthrough album That's the Way of the World. "Sing A Song" was built around a riff that their guitarist Al McKay came up with in the dressing room during a gig. McKay finished writing the song with group leader Maurice White, who kept the lyrics simple - a joyful message about the power of song. White produced the track with Charles Stepney, who he worked with as a staff musician at Chess Records in Chicago when White was a drummer and Stepney played piano and did arrangements. On this track, they created a sound similar to what they often did at Chess on records for Betty Everett, Etta James and Fontella Bass.
Gratitude was a double album, but only one side was recorded in a studio - the other three sides were live recordings since the band was so busy on the road they didn't have time make another full studio album. "Sing A Song" was one of the studio cuts, and it helped the album sell over 3 million copies, and preparing the musical world for Peter Frampton's Frampton Comes Alive, which was released a few months later.
