About the Song

Mother cannot guide you, now you're on your own
Only me beside you, still you're not alone
No one is alone, truly no one is alone

C - Fmaj7 - / C - Fmaj7 - / F - - - 

Sometimes people leave you halfway thru the wood
Others may deceive you, you decide what's good
You decide alone, but no one is alone

Mother isn’t here now (wrong things, right things)
who knows what she'd say? (who can say what's true?)
Nothing's quite so clear now (do things, fight things) feel you've lost your way? (you decide)
But you are not alone, believe me, no one is alone (no one is alone, believe me) truly

You move just a finger, say the slightest word
Something's bound to linger, be heard
No one acts alone, careful, no one is alone

(bridge) People make mistakes, fathers, mothers, people make mistakes 
Holding to their own, thinking they're alone
Honor their mistakes, fight for their mistakes, everybody makes one another's terrible mistakes
Witches can be right, giants can be good, you decide what's right, you decide what's good
Just remember (x2)

F - - - (4x) F -

Someone is on your side (our side x2), someone else is not
While we're seeing our side (our side x2), maybe we forgot
They are not alone, no one is alone

Hard to see the light now, just don't let it go
Things will come out right now, we can make it so
Someone is on your side, no one is alone
