Hey, so a very talented singer on the internet did this cover of Tje Rains of 
Castamere, but she hadn't written down the chords, so I had a go. 

Capo 1

Am                   G          Am
But Who are you? The Proud Lord said
F           G      Am
That I must bow so low
Am               G         Am
Only a cat, of a different coat
F              G       Am
That's all the truth I know
F                  Gm
In a coat of Gold, In a coat of red
Gm                    F
A lion still has it's claws
Am                   G          Am
And mine are long, and sharp my Lord
F           G         Am
As long and sharp as yours


Am                   G     Am
And so he spoke, and so he spoke
F            G    Am
That Lord of Castamere
Am                       G       Am
But now the rains, weep o'er his hall
F           G        Am
with no one there to hear
F                    Gm
The rains fall down, yes the rains fall down
Gm              F
on Lord of Castamere
Am                        G      Am
Yes now the rains, weep o'er his hall
F          G      Am
And not a soul to hear.
