The Stanley Brothers, who contributed to "O Brother, Where Art Thou," had a song called "Harbor of Love" that mentioned "the great judgement morning." There are several hymns that contain the phrase.
HARBOR OF LOVE

There's coming a time on the great judgement morning
When the Savior will welcome you home.
Will you be prepared for the journey to Heaven
On the great ship that carries God's chosen ones home?

Oh, the water's so deep (oh, the water's so deep
On the rier of Jordan (on the river of Jordan),
And the light shines so bright (and the light shines so bright)
From the heaven above (from the heaven above)
And the midnight has passed (and the midnight has passed)
A new day is dawning (in heaven on high).
Oh, the great ship will anchor (oh, the great ship will anchor)
In the "Harbor of Love."

If you're wandering in sin away from God's teaching,
Won't you ask him to show you the way?
Fall down on your knees in a chapel next Sunday
And meet all your friends up in heaven some day.
