Debby Boone - "You Light Up My Life" (1977)

"You Light Up My Life" is a ballad written by Joe Brooks, and originally recorded by Kasey Cisyk for the soundtrack to the film of the same name. The song was performed in the film by its lead, Didi Conn, who lip synched Cisyk's version.


Debby Boone, was recruited to record the single, which became a massive success, topping the Billboard Hot 100 chart for a record-setting ten consecutive weeks. It easily became the most successful single of the 1970s in the United States, and set a new Hot 100 record for longest reign at No.1. (Elvis Presley's double-sided "Don't Be Cruel/Hound Dog", then recognized as the longest-running No.1 of the rock era, spent eleven weeks atop the Billboard Best Sellers chart in 1956, before the debut of the Hot 100.)


The record was matched in 1982 by Olivia Newton-John's Physical, but never surpassed until a 1991 change in chart methodology allowed songs to achieve longer reigns at No.1 ("End of the Road" by Boyz II Men set the new record, thirteen weeks). The single, which was certified platinum by the Recording Industry Association of America (RIAA), also hit #1 on the Adult Contemporary chart and reached #4 on the Country chart. Conversely, the single peaked at #48 in the UK Singles Chart.


Although written by Brooks as a love song, the devout Boone interpreted the song as inspirational and proclaimed that it was instead God who "lit up her life."


Cisyk's soundtrack recording was released as a single to bolster sales of the soundtrack, after Boone included her version on her first solo album also entitled You Light Up My Life. (Although the soundtrack was certified gold, peaking at No. 17 on the Billboard 200 albums chart, it never included Boone's version of the song.)


Cisyk's single was credited to "Original Cast", not to Cisyk herself, and only reached No. 80 on the Billboard Hot 100. Brooks also released an instrumental version of the song from the soundtrack as a single, but his version failed to chart.


Debby Boone's success resulted in Grammy nominations for Best Pop Vocal Performance Female and Record of the Year and won her the 1977 Grammy for Best New Artist and the 1977 American Music Award for Favorite Pop Single. The song earned Brooks the 1977 Song of the Year Grammy (tied with "Love Theme from "A Star Is Born" (Evergreen)") as well as the Best Original Song awards at the 1977 Golden Globe and Academy Awards.


The song ranks #7 on Billboard's All Time Top 100. More recently, Matthew Wilkening of AOL Radio ranked Boone's version of the song at #51 on the list of the 100 Worst Songs Ever, telling the listener that their grandparents "probably love [the song] and consider it a hip new record," before warning said listener not to judge their grandparents too harshly.
