Oh, yes, please.
I have been reading the fic and thought of two songs that would be perfect to the Arthur and Lancelot's mood where you left off, I will try to translate the first track:

Alone, without you
I'm walking
And don't know what to do
Neither heaven answered me
When I asked for you, my darling

I could not forget you
Since the night I lost you

Shadows of doubt and jealousy
just thinking of you surround me

Let me find you
and if I find you
come back again

Forget the past
no longer remember that yesterday

While I'm asleep
I dream the two close together to a blue sky
But when I awake the sky is red
I'm needing you

The other song I'll post it when I find the lyrics, :P

Bye bye
