I used to listen to this one repeatedly on my parents' record player when I was five or six. The chorus melody struck me in such a curious way. It was one of the first songs I can remember singing along to, with tonality.
Now an old guy, I still love the chorus, but I most love the upper-register web of keyboard, bass, and vocal criss-crossing each other in the verses. The middle bridge takes a cool turn, then resolves in kind of a sweet blunt way back into the chorus.
There is not much else to this song. A sax solo comes in at the end due to contractual obligations with the '80s.
If you had a smooth little drum machine part and just a few other instruments to spare, there is no chance you assemble them all into a song this good. Hand a songwriter like prime Phil Collins just a tambourine and a kazoo, and you would get at least a quality B-side.
