"
You Light Up My Life" is a
ballad written by
Joseph "Joe" Brooks, and originally recorded by
Kasey Cisyk for the
soundtrack album to the 1977
film of the same name.
[1] The song was
lip synched in the film by its lead actress,
Didi Conn. The best-known version of the song is a
cover by
Debby Boone, the daughter of singer
Pat Boone, which held the #1 position on the
Billboard Hot 100 chart for ten consecutive weeks in 1977, setting a new record for that time. She topped
Record World Magazine's Top 100 Singles Chart a record of 13 weeks on that magazine's charts.

Decades after its release, the Debby Boone version is still considered one of the top ten Billboard Hot 100 songs of all time. In 2008, it was ranked at #7 on
Billboard's "Hot 100 All-Time Top Songs" list (August 1958 - July 2008).
