Actually a really happy carol- 'Who has no song to sing within his heart... let him be gone with his doom and gloom...' celebrating the joys of the season, alcohol and keeping warm among other nice things.
Doom and Gloom
Who has no song to sing within his heart?
Who has no song to delight him?
Let him begone with his doom and gloom and we will sing.
Sing because our joys are great
Though winter's on the land.
Sing because we celebrate that
Chris is born to man.
Sing because the nights are long
And love keeps out the cold.
Sing because the ale is strong
And we feel we'll never grow old.
Sing for love of singing
And the music in our bones,
Sing for love of friend and stranger
And health and hearth and home.
