We used to sing this in elementary school. Web search says it’s Henry Wadsworth Longfellow.

All these decades later and it will sometimes still pop into my head, while driving, while cycling, while having a tense moment at work.

Stars of the Summer Night

1. Stars, stars of the summer night,
   Far, far in yon azure deeps
   Hide, hide your golden light,
   She sleeps, my lady sleeps.
   She sleeps, she sleeps, my lady sleeps.
2. Moon, moon of the summer night,
   Far, far down yon western steeps
   Sink, sink in silver light,
   She sleeps, my lady sleeps.
   She sleeps, she sleeps, my lady sleeps.
3. Wind, wind of the summer night,
   Where yonder woodbine creeps,
   Fold, fold thy pinnions light,
   She sleeps, my lady sleeps.
   She sleeps, she sleeps, my lady sleeps.
