A Small Fruit Song
Said the apple to the orange:
"Oh I wanted you to come
Close to me and kiss me to the core
Then you might know me
like no other orange
Has ever done
before"

Al Stewart

This song has been performed with various subtle variations and preceded by guitar solos, ranging from seconds to minutes.
After only 34 words, this song has nothing else to say and to Al Stewarts eternal credit, that's where he stopped. Its power is in its brevity.
