CANNONBALL by Supertramp. When you think of Supertramp, it’s probably Roger Hodgson’s falsetto you hear in your head. That’s why most figured the band was doomed when he split in 1983, but the rest of Supertramp was able to soldier on for a couple more albums with Rick Davies handling the vocal chores. This 1985 effort, though, was pretty much their last hurrah before they disbanded in 1988.
I think this video inspired Geico to use cavemen in their ads: Cannonball
