The Simplicity of Her Majesty

I just had an epiphany about “Her Majesty”, the “hidden” song fragment at the end of The Beatles’ “Abbey Road” album:

This song is not a fragment.

At 23 seconds in length, it is a complete song. It has a full-fledged structure, A-A-B-A (verse-verse-bridge-verse), just like millions of regular-length songs. Its bridge advances the story in another direction from the verses, before returning to the original theme in the final verse. “Her Majesty” is an elegant example of compactness and simplicity.

I challenge you to write a complete song as compact as “Her Majesty”.
