Music for the End of the World (Updated!)

We all know the hymn O Come O Come Emmanuel. A few weeks back I mentioned Family Radio is now playing a version with different lyrics about judgment day. The familiar chorus has been altered in this way:

"Rejoice, Rejoice, Emmanuel" is now: "May twenty, first, two thousand eleven"

Here is an mp3: O Come May 21

Song Lyrics

The Lord will come to judge the Bible tells.
Prepare to meet thy God, Oh, Israel.
The time has been disclosed, the Book unsealed.
The date of Christ's return has been revealed.

[Chorus]
May 21, 2011, the saints will be caught up to heaven.

Listen to the watchman sounding.
Warning of a judgment at hand.
This dying world with sin is abounding
From wanton pride of fallen man.
Christ will come to earth to judge the world of sin.
Salvation will have come to an end.

The earth will quake as nations fall.
Too late for those who would not heed the call.
The trump has blown but grace remains today.
Cry out for mercy on your knees and pray.

[Chorus]
