The acoustic version of this song from A&B's Acoustic album is absolutely 
beautiful and I just had to tab it, so here it is!
Had a little help from Chordify:

The intro tab can be played throughout the song,I just like the sound of strumming more!

Goodbye to you

Dm                G
In my heart of hearts
Dm                G
I know there's more love left for you

Screams
F                G
Oh if it's screaming out loud

I'll be screaming for love
F                G
Love is not enough
