It can't be wrong. ... When it feels so right

Debby Boone didn't sing the main song in the movie. Neither did the actress, Didi Conn. Some unknown singer, whom I don't know the name of, did the movie vocal track.

 

Kasey Cisyk if Wiki can be believed.

EDIT: Fixed for Bubbler

 

Who did she screw to get that gig?

 

That's exactly who it was, Wiki or not.

 

Oh, geez, who knows - maybe one of the billions of people who heard her sing on various works, primarily commercials, jobs that made hers "the most ubiquitous voice in the land."

She worked as a backup singer for Carly Simon and Quincy Jones; she dubbed the Oscar-winning title song for the 1977 movie ''You Light Up My Life,'' and in the demanding world of commercial jingles, she was a star, one whose very anonymity was a critical asset.

It allowed her, for example, to amass a list of credits that included such archrivals as ABC, NBC and CBS; McDonald's and Burger King, American and Delta airlines and even Coke and Pepsi.

And for all her long run with Ford, Miss Cisyk also sang in the service of Chevrolet, Cadillac and Toyota.

It was her work for Ford that made her the envy of her colleagues. From the time she became the voice of Ford in 1981 until the campaign was finally retired two months ago, hers was the most ubiquitous voice in the land. In 1989, when the campaign was nearing the midpoint of its 17-year run, an industry record for a corporate soloist, Ford executives estimated that Miss Cisyk had been heard by a cumulative audience of 20 billion.

 

So this dude wrote one of the worst, sappiest piece of shit songs ever and he's a pervert.

 

Right now I'm asking myself, "Why the hell did I open the Wikipedia page for You Light Up My Life?" What would possess me to do such a thing?

Whew! Thank God it was a dead link. That was a close one!

 

I fixed it for ya, Bub!
