I saw that video recently and was struck by how long ago it looked. All videos from the early MTV era look like they’re from another time but for some reason that one really stands out. I think because it’s from the absolute earliest of the early era, even slightly pre MTV as you mentioned, and also all the candid low-budget location shots with the old cars.
In the first draft of my original comment, I actually made the exact same observation you made about the production quality of the video for Our Lips Are Sealed.
I decided that sounded too much like criticism, so I deleted that part to avoid a Free Republic backlash.
