Official Lyrics
(if there are any mistakes in the lyrics, its in the official booklet)
the snow has come down on top of everything.
the town is alive and well without you.
the lights they pier out, of the leafless trees.
and you won't be alone, i am beside you.
true love, the stars in the sky illuminate below,
the light is the sign that love will guide you home.
the stars in the sky illuminate below,
if the world were to die, the light will guide you.
tears spilling out across a dead end street,
your house is a lonely box that holds you.
a star, bright and loud, is in dire need,
of that fear, it is an empty fear inside you.
true love, the stars in the sky illuminate below,
the light is the sign that love will guide you home.
the stars in the sky illuminate below,
if the world were to die, the light will guide you.
