This bright anthem is about U2's transformative first trip to California in the early 1980s. It is one of a number of personal tracks on Songs of Innocence. Bono told Rolling Stone: "The whole album is first journeys - first journeys geographically, spiritually, sexually. And that's hard. But we went there."
Other US-location-named U2 songs include the Pop track "Miami" and the All That You Can't Leave Behind cut "New York."
"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.
