There's A God In Heaven. He's Watching me Squirm

Don't be far tonight,
Or I swear I'll let the smoke swallow me
In deep controlled breaths,
You're cunning and clever, and soon to leave me
Looking after the sky,
But it doesn't matter-
Not while I lay on the hood of this car or any other,
Not tonight
Or any other night,
I exist only now, not forever,
You are true I am absent,
And when you come again to find me
You'll find me;
Just another fish in the brook-
Swimming against the stream.
