hey say we are what we are
But we don’t have to be
I’m bad behavior but I do it in the best way
I’ll be the watcher (watcher) of the eternal flame
I’ll be the guard dog of all your fever dreams
(oh...) I am the sand in the bottom half of the hourglass. (glass, glass)
(oh...) I’ll try to picture me without you but I can’t
 [bad word] 
'Cause we could be immortals, immortals
Just not for long, for long
And if we meet forever now, pull the blackout curtains down
Just not for long, for long
We could be immortals, immortals, immortals, immortals
(Immortals)

Sometimes the only payoff for having any faith
Is when it’s tested again and again everyday
I’m [bad word] your past to my future
It might be your wound, but they’re my sutures

I am the sand, bottom half of the hourglass. (glass, glass)
I’ll try to picture me without you but I can’t
 [bad word] 
'Cause we could be immortals, immortals
Just not for long, for long
And if we meet forever now, pull the blackout curtains down
Just not for long, for long
We could be immortals, immortals
Immortals

And if we meet forever now
Pull the blackout curtains down
We could be immortals, immortals
Just not for long, for long
We could be immortals, immortals, immortals, immortals
