The fifth and final season premieres Sunday, January 6, although if you have HBO On Demand, you can see it right now - each new episode premieres on HBO On Demand 6 days before it premieres on HBO, with the exception of the series finale.

To honor the one of the best dramas on TV today, here are the lyrics to the opening theme song (full version):

When you walk through the garden
You gotta watch your back
Well, I beg your pardon,
Walk the straight and narrow track.
If you walk with Jesus,
He's gonna save your soul
You gotta keep the devil
Way down in the hole
He's got the fire and the fury
At his command
Well, you don't have to worry
If you hold on to Jesus' hand
We'll all be safe from Satan
When the thunder rolls
Just gotta help me keep the devil
Way down in the hole
All the angels sing
about Jesus' mighty sword.
And they'll shield you with their wings
and keep you close to the lord.
Don't pay heed to temptation
for his hands are so cold.
You gotta help me keep the devil
way down in the hole
