A Whistling Tune Lyrics

Did you ever notice when the sun goes down
Out of nowhere comes a strange and pretty sound
It's a whistling tune for walking in the night
If you listen you can hear it in the breeze
Specially when the breeze is drifting through the trees

[ Lyrics from: http://www.lyricenter.com/e54777-elvis_presley~a_whistling_tune_lyrics.html ]
It's a whistling tune for walking in the night
And the murmuring waters sing the song
The echoing mountains hum along
The whispering valleys fill the air
With a whistling tune our hearts can share

It's so wonderful to walk beneath the moon
Listening to old mother nature's favorite tune
It's a whistling tune for walking in the night
