Help me ID this Yacht Rock-sounding song

So I walked into a Dollar Tree and heard the last 20 seconds of a late '70s/early '80s midtempo Yacht Rock-sounding tune. It had switched into pretty much an instrumental at that point, with a Peter Cetera-sounding voice chiming in with (I think) the vocal "ninety-nine" and nothing else. (It was not "99 Red Balloons.") There might have been some funky slap bass thing going on.
<br>
<br>This song must have been a minor hit back in the '70s or '80s... because that was the last time I heard it.
<br>
<br>Any ideas?

That's it! Thank you :)

This sounds like something they would play at Dollar Tree! Are these guys for real? I like the idea of wearing all white, it should come back in style. Even the glasses are white!

You guys suck. This song won't leave my head now.

Will this help?

Kinda scary to think that there's been a thin piece of brain tissue behind my skull that's been sitting dormant for 20 years, just waiting for you to come along and wake it up.

Soon as I saw that chalk outline start dancing, I was all "Just watch, he's gonna do a backflip."

Such was the ridiculous state of my 13 year old mind that when said song was a hit -- which was right around the time Dune came out, which they of course did the soundtrack for -- I figured this song was their way of telling the story of the film in a pop song equivalent. Must have been the "Young girls say he's Jesus" line.

Will this help?

You know, I'd forgotten this, especially the Ultravox "Sleepwalk" sequencer.
