In 1977, Billboard magazine published a chart ranking the top-performing songs in the United States in the easy listening or middle of the road market.
Carly Simon had the year's longest run in the top spot, spending seven weeks at number one with "Nobody Does It Better", the theme song from the James Bond film The Spy Who Loved Me.
Streisand's other number one of 1977, "My Heart Belongs to Me", had also been written for the film A Star Is Born but was ultimately not used,[4] and was instead included on her album Superman.
Although the song was sung in the film by Kasey Cisyk, Boone was brought in to record a new vocal over the existing instrumental backing track and this was the version that achieved chart success.
In addition to "You Light Up My Life", several of 1977's other Easy Listening number ones had sufficient crossover success to also top the Hot 100, including songs by Mary McGregor, Leo Sayer, David Soul, Barbra Streisand, Barry Manilow and the Bee Gees.
