You Light Up My Life (1978)
The movie that used to be aired on cable constantly they gave birth to that Infamous song.
Jennifer Gibbons commented
You Light Up My Life is a 1977 American romantic drama film written and directed by Joseph Brooks and starring Didi Conn, Joe Silver, and Michael Zaslow.The plot concerns a young woman named Laurie (Conn) with dreams of becoming a singer who soon finds herself pressed by young friends to sing and her father, who wants her to be a comic.
why you should riff it:
1. Didi Conn is a national treasure.
2. The song is an earworm.
3. Who know Conn could lipsynch so well??
