"The Power of Love" is a 1985 single by Huey Lewis and the News, written for and featured in the 1985 blockbuster film Back to the Future. The song became the band's first number-one hit on the U.S. Billboard Hot 100 and their second number-one hit on the U.S. Mainstream Rock chart. In the United Kingdom, it was released as a double-A side with "Do You Believe in Love", becoming the band's only top ten hit on the UK Singles Chart. The song is included alongside "Back in Time" on the film's soundtrack, and appears as a bonus track on international editions of the band's fourth studio album, Fore!.
Huey Lewis was approached to write a theme song for the film. He met with Bob Gale, Steven Spielberg, and Robert Zemeckis, from the film's production team, who intended that the band be Marty McFly's favorite band. Though flattered, Lewis did not want to participate because he did not know how to write film songs and did not want to write one called "Back to the Future". Zemeckis assured Lewis he could write any song he wanted. Lewis agreed to submit the next song he wrote, which was "The Power of Love". The lyrics do not make any mention of the film's storyline.
