Lyrics:

You ask how long I'll love you
It's hard to explain but I'll try
Tell me how long has the sun been shining
Above us in the sky?

Till the last day of forever,
If I have it my way we'll stay together
Till the rivers run dry I'll be loving you.
Till the mountains have crumbled
I'll always be true
And if for some reason you say goodbye
Ask me how long I would cry
Till all the rivers run dry

This path that we're walking
May be rough and rocky sometimes
But we'll believe in one another
Whatever we find

And when you need a hand to guide you
I will be there walking beside you
Till the rivers run dry
