Joey Scarbury - The River's Song (River Rat OST, 1984) 

Unknown masterpiece. Just like the movie for which it serves as OST, though. ;) No infringement intended.
THE RIVER'S SONG (1983, Lyrics, Transcript by ear)
Follow me! - whispers the river's song,
Come back to me!... - softly she sings,
Gently she brings me home
C: And the tears are washed away
On the tide of a slow-movin' dream
Where she rocks me to sleep while she sings
The river's song.
Stay with me! - whispers the river's song.
Come away with me! - Follow your heart,
Reach out your hand and hold on!
C: The wind begins to rise,
As it carries my soul on its wings,
Above the shimmering water that sings
The river's song.
Secrets run deep
And she hides them beneath her smile.
She's as silent as sleep
Till the rain and the thunder
Rise up, and drive her wild...
Oh, won't you follow me? - whispers the river's song!
Come back to me! - softly she sings,
Gently she brings me home!
C: The tears are washed away
On the tide of a slow movin' dream,
Where she rocks me to sleep while she sings
The river's song.
