She has no voice for in this world
She can't be heard but my sister sings

She understands that in this world
It all must change so my sister sings

And I can't always hear her
I'd be smarter if I could
For she knows the secrets of this life
And the times that I'm near her are so good

Oh, my sister sings. Oh, my sister sings

Long ago when the earth was young
They all could hear my sister sing
Now no one hears the one that tries to teach us
What we were born knowing
