Here is the second Christmas Mane 6 Acapella. This is my arrangement of the classic Christmas Carol; We Three Kings (Tribes)
Lyrics are down below:

Rainbow Dash, Rarity and Pinkie Pie:
We three tribes of Equestria
Bearing feuds we've travelled afar.
Field and fountain, moor and mountain,
We must all stay apart.

Mane 6:
O Windigos that freeze our home,
Left us cold and left to roam,
Westward leading, still proceeding,
Guide us to our perfect home

Rainbow Dash and Fluttershy:
First there comes the pegasi
We've been gifted with great flight
We have suffered through our hunger
No matter how hard we've tried

Mane 6:
O Windigos that freeze our home,
Left us cold and left to roam,
Westward leading, still proceeding,
Guide us to our perfect home

Rarity and Twilight Sparkle:
Then we have the unicorns
Glowing magic with our horns
We have magic though it's tragic
The weather is frozen born

Mane 6:
O Windigos that freeze our home,
Left us cold and left to roam,
Westward leading, still proceeding,
Guide us to our perfect home

Pinkie Pie and Applejack:
Lastly there's the ponies of Earth
Without wings or horns in our birth
Though it's cheesy, we are freezing
We have to find new turf

Mane 6:
O Windigos that freeze our home,
Left us cold and left to roam,
Westward leading, still proceeding,
Guide us to our perfect home

Twilight Sparkle, Fluttershy and Applejack:
Wait you leaders, we mustn't fight
This is why we have chilly nights
If we stop the cold weather and stick together
A new land will see the light

Mane 6:
O Ponies of Equestria
We have all come very far
Westward leading, stopped proceeding
Guide us to Equestria
