The Union is a collaborative album between British singer-songwriter Sir Elton John and American musician Leon Russell. Produced by multiple-Grammy winning producer T Bone Burnett, this was the first track to be recorded by the two stars. Elton explained to Rolling Stone how it was inspired by a gospel legend: "We had just convened in the studio. T Bone put up a YouTube clip of Mahalia Jackson, and it inspired us. I went to the piano and started writing. Leon came and played it with me – two pianos, two voices. It broke the ice."
"St. Elmo's Fire (Man In Motion)" was not written for the movie, but for Rick Hanson, a wheelchair athlete whose 1985 "Man In Motion" tour logged 24,856 miles on his wheelchair in 34 countries while raising $26 million for spinal cord research.
