Verse
Life is so unpredictable
People come, people go
Is there anything that's for sure?
You don't know, I don't know
In a world where we don't believe, in fairy tales, they don't come true
It's good to know in your time of need that you've got something to hold onto 
Chorus 
I can't promise the moon
I might just play out of tune
But I will always be true, this is my promise to you, this is my promise to you
I'll be the light that shines through your darkest days 
The one true voice that you won't mistake
When you're lost, I'll be a familiar face
This is my promise to you this is my promise to you
Verse
What becomes of a broken heart, where does it go? Where does it go?
Will it heal or just fall apart, you don't know, I don't know
You can't be afraid to try when you fall you can get up again
All that you need to know is that you're not alone I'll be your friend
Chorus 
I can't promise the moon
I might just play out of tune
But I will always be true, and this is my promise to you, this is my promise to you
I'll be the light that shines through your darkest days 
The one true voice that you won't mistake
When you're lost, I'll be a familiar face
And this is my promise to you this is my promise to you
I'll be the sweet remembrance of days gone by
The song that comforts you when you cry 
Until the end I'll be by your side 
And this is my promise this is my promise to you
I don't know what else to do 
This is my promise to you
