The song was backed with the Mick Jones song "I Have Waited So Long". It proved to be their sixth Top 40 single in two years. The song was written by the songwriting team of Lou Gramm and Mick Jones, and reached number 15 in the charts in the U.S. and 45 in the U.K. "Blue Morning, Blue Day" is also available as downloadable content for the Rock Band series and was released on clear blue vinyl.
Gramm said about the song, "It talks about a young musician that's burning the candle at both ends. He has a lot on his mind, and walks the street at night." Blue is used as a metaphor for misery. The color was later in a different context on Gramm's 1987 solo hit "Midnight Blue".
