Lyrics:

If you go away
On a summer day
Then you might as well
Keep the sun away
All the birds that flew
In the summer sky
And our lovers knew
And our hearts were high
And the days were young
And the nights were long
And the moon stood still
With the night birds song

If you go away (3)

But if you stay
I'll make you a day
Like no day has been
Or will be again
Well sail on suns
Well ride on the rain
Well talk to the trees
Well fly with the wind

But if you go away
And I love you so
They'll be nothing left
In the world you know
Just an empty moon
Full of empty space
Like an empty look
I see on your face

If you go away (3)

But if you stay
Ill make you a day
Like no day has been
Or will be again
Well sail the suns
Well ride on the rain
Well talk to the trees
Well fly with the wind

If you go away (3) (less info)
