This spiritual is in the DT, song id 2954, copied from Lloyd and de Ramon y Rivera, p. 95, Folk Songs of the Americas, 1965, Novello and Co., London. This printing lacks an instruction found in both "Negro Spirituals, or the Songs of the Jubilee Singers," No. 11, and in G. C. Noble, "The Most Popular Plantation Songs," 1911, Hinds, Noble and Eldridge, NY, p. 83.
In thread 52566, an article on the Fisk Jubilee Singers in the "American Heritage" magazine, 2000, parts quoted by Wilco48 in thread 52566: Fisk Singers , says George L. White, Civil War veteran, song collector and first director of the Fisk Singers, collected "I'll Hear the Trumpet Souns" from Jennie Jackson, a former slave.
Published verses are similar in content. Are there any variants?

The missing direction reads: "Repeat the music of the first strain for all of the verses but the first." Only the first two verses are given completely below, to show how the parts of this repetitive spiritual fit (camp-meeting song?).

Lyr. Add: I'll Hear the Trumpet Sound

First strain:
You may bury me in the East,
You may bury me in the West,
But I'll hear that trumpet sound
In that morning.

1. Father Gabriel in that day
He'll take wings and fly away,
For to hear the trumpet sound
In that morning.
You may bury him in the East,
You may bury him in the West;
But he'll hear the trumpet sound
In that morning.

Chorus:
In that morning, my Lord,
How I long to go,
For to hear the trumpet sound
In that morning.

2. Good old Christians in that day,
They'll take wings and fly away,
For to hear the trumpet sound
In that morning.
You may bury them in the east,
You may bury them in the West;
But they'll hear the trumpet sound
In that morning.

You may bury me in the East,
You may bury me in the West;
But I'll hear the trumpet sound
In that morning.

Chorus:
In that morning, my Lord,
How I long to go,
For to hear the trumpet sound
In that morning.

3. Good old preachers in that day,
They'll take wings and fly away, etc.

First strain and chorus:

4. In that dreadful judgement day,
I'll take wings and fly away, etc.

First strain and chorus:

Other 19th c. spirituals with mention of the trumpet are "In the Morning" (Higginson) and "Where Shall I Be When de Firs' Trumpet Soun'?" Neither one seems to be in the DT or threads.
