Being a fisherman of sorts the best way to explain needing a chorus is, that is where the "hook" normally resides. That would be the lyrical hook. The hook is what catches your audience by the ear. Its the part of a song that rattles around in everyone's head long after the song has ended. Probably because its repeated often.

There are also musical hooks, series of notes that catch your attention. So, who needs a chorus? A good song is a good song. Its all subject to interpretation, there are lots of good tunes that don't need any chorus, especially some ballads I've heard.

Anyway, an important part of any song is to include some kind of hook, be it lyrical or musical. There is no law that I'm aware of that requires a chorus. JMHO
