Has anyone ever heard of this song or know anything about its origin?

Nobody knows when the rain 's gonna stop fallin'
No one knows for sure sure when the sun will shine through
One thing we all know
That's the rain won't fall forever
On the green golden valley
or the valley would turn blue

Ask of the lily, lily of the valley
Where'd you get you color and how'd you put it on.
She'll say the sun it was that gave her her melody
She'll say the sun it was her color all along.
