Live August 1987. This was featured in the movie Back to the Future and included on the soundtrack. It plays in a scene where Marty McFly (played by Michael J. Fox) hears it as he rides his skateboard from Doc's house to school. The film's director Robert Zemeckis wanted Lewis to do the song - Huey Lewis & the News were rising stars with a modern sound that worked well in the movie, which takes place in both 1955 and 1985. Lewis had never done film work and hesitated at first, since he didn't want to write a song called "Back to the Future." When Zemeckis told him that the song didn't have to be about the movie, Lewis accepted the challenge.
The song has a very universal message that works very well outside of the film. Lewis was newly married and had two young children when he wrote it with his bandmates Johnny Colla and Chris Hayes. His family provided inspiration for the lyrics. Lewis was working on this song while the movie was in post production. By the time Lewis delivered the song, most of the scenes were mixed; the only place the song worked was the scene where Marty is on his skateboard going to school. This scene has nothing to do with the power of love, but music fits the vibe and works in context.
