Misc Unsigned Bands - Andrew Simple - I Got Your Back chords

hey this song is from the geek squad commercial and I thought it would be an easy song 
to tab. simple chords. first tab and I'm not 100% sure it's right.

Capo on fourth fret.

C              G                 Am         F
We we're not meant to be alone

We're vowed a little help to get along

So never get to thinking no one's there for you

Just let me know I'll come to your rescue

F               C               G
So anytime you need a helping hand
F               C               Am
You'll find in me a faithful friend
            F      C      G   pause
Yes I'll always be there

I got your back
F            C G Am F
I got your back
