Third Trumpet, Fourth Trumpet Sounding

I only heard the first and third
But I saw them fall
The stars and all
I think I lost my brother this time

The fourth will come
Darken the sun
But not all of it
We'll have some left
To get a tan and learn the name Apollyon

Soon they'll come
Euphrates' sons
They've waited long
Watched everyone
As they laughed and lay in the sun

And when they're done with everyone
With man and wife, daughter and son
Will you still not care what you've done?
