Dweezil and Moon Unit were the elder children of Frank Zappa, and frequent MTV VJs. They did a couple of singles together - this Dweezil-penned antiwar song being their best known collaboration, from 1986, when it received a lot of MTV airplay. Look for the Frank Zappa cameo at around the 2:03 mark of the video, by the way - as well as a LOT of other celebrity cameos (I count no less than 6).
I was a teenage boy. I was watching for Moon Unit.
By the way, Dweezil was 17 in this video, and reportedly wrote this song when he was 15. The WHOLE song - lyrics and music.
Moon Unit, of course, is better known for her appearance on their father's single "Valley Girl", but this is an objectively better song.
