The Russian song that is played various of times during the series.

[first brother]
Forgive me, little brother
This is all my fault
There's no way to bring back
What has already gone to the earth

One who knows the truth of life
Could have told me the answer
I made a terrible mistake
There's no cure for death

[together]
Beloved mother, soft and gentle!
We loved you so much
We wanted to see you once more
But all our strength was wasted

[first brother]
I led you here
Following a beautiful hope
Now we can never go back
My brother, it's all my fault

[second brother]
Don't cry, don't be sad, older brother
You are not the only one at fault
We will walk this road together
We will pay our debts

I don't blame you
I am not mad at you
Our sins are so heavy
We must be strong

[together]
Beloved mother, soft and gentle!
We loved you so much
We wanted to see you once more
But all our strength was wasted

[second brother]
It was my own fault
To follow a beautiful hope
I never blamed you
My brother, you are not alone

[together]
We can never forget
But we can never go back
What the earth takes is gone
We must go forward now

[first brother]
Prosti menya, mladshiy brat!
Ya tak pred toboy vinovat.
Pyitatsya vernut' nyelzya
Togo, chto vzyala zyemlya.

Kto znayet zakon Byitiya,
Pomog byi mne nayti otvet.
Zhestoko oshibsya ya;
Ot smerti lekarstva nyet.

[together]
Milaya mama! Nyezhnaya!
Myi tak lyubili tebya.
No vse nashi silyi
Potrachenyi byili zrya.

[first brother]
Tebya soblaznil ya
Prekrasnoy nadezhdoy
Vernut' nash semeynyiy ochag.
Moy brat, ya vo vsem vinovat.

[second brother]
Nye plach', nye pechal'sya, starshiy brat!
Nye tyi odin vinovat.
Doroga u nas odna,
Iskupim vinu do dna.

Mnye nye v chem tebya upreknut'.
I ya nye obihen nichut'.
Tyazhek, nash gryekh
Khotet' byit' silneye vsekh.

[together]
Milaya mama! Nyezhnaya!

Potrachenyi byili zrya.

Ya sam soblaznilsya
Prekprasnoy nadezhdoy
Vernut' nash semeinyiy ochag.
Ya sam vo vsem vinovat.

[together]
No chto zhe nam delat', kak byit'
Kak vse ispravit', zyabyit'
Pyitat'sya vernut' nyel'zhya,
Togo, chto vzyala zyemlya.
