I'm looking for this popular song from the 80's.  I think it's called
Keriou Keira or something like that.  The chorus is something like
this "Keriou Keira on the road that I must travel....Keriou Keira on a
highway in the night..."  I know this sounds completely random and
dumb, but do you have any idea what I'm talking about?

I am certain that the song you're looking for is "Kyrie," which was a
big hit for a group called "Mr. Mister" in the 1980s. The phrase
"kyrie eleison" (pronounced like KEER-ee-ay el-AY-son) is repeated
several times in the chorus:

Kyrie eleison, 
down the road that I must travel
Kyrie eleison, 
through the darkness of the night
Kyrie eleison, 
where I'm going will you follow
Kyrie eleison, 
on a highway in the light...

"Kyrie eleison" is a phrase that is well known to most Catholics. It
is Greek for "Lord, have mercy (upon us)."

You'll find the song on the CD "The Best of Mr. Mister". You can
listen to a clip of "Kyrie" here, to verify that it's the right song:

clarification; I'll be glad to offer further assistance before you
