Beautiful Dreamer a poem by Stephen Foster  

 
 
Beautiful dreamer, wake unto me,
Starlight and dewdrops are waiting for thee;
Sounds of the rude world heard in the day,
Lull'd by the moonlight have all pass'd away!

Beautiful dreamer, queen of my song,
List while I woo thee with soft melody;
Gone are the cares of life's busy throng.

Beautiful dreamer, awake unto me!
Beautiful dreamer, awake unto me!

Beautiful dreamer, out on the sea,
Mermaids are chaunting the wild lorelie;
Over the streamlet vapors are borne,
Waiting to fade at the bright coming morn.

Beautiful dreamer, beam on my heart,
E'en as the morn on the streamlet and sea;
Then will all clouds of sorrow depart,

Beautiful dreamer, awake unto me!

This was my daddy's favorite melody  when I was a child.  He whistled beautifully  and I can remember hearing him whistle "Beautiful Dreamer often.
