Ellen Jane Lorenz, in her Glory, Hallelujah!: The Story of the Campmeeting Spiritual (Abingdon, 1978, p. 121), writes (underline added):

Say, brothers, will you meet us illustrates the singability of the campmeeting choruses; it is the campmeeting chorus most parodied, from the time of its first creation up to the present. ... L.A. Banks relates its story in his Immortal Songs of Camp and Field [1898]. His first meeting with the song was in Charleston in 1859, with a performance soon after at the YMCA of Albany, N.Y. (But the present study reveals a publication in Songs of Zion, 1851.) Banks says, "It has been claimed that the Millerites [Adventists] used the tune to a hymn, 'We'll see the angels coming through the old church yard (3 times) / Shouting through the air / Glory, glory, hallelujah.'"
