I checked the Roud index. All 109 entries with Source containing Green Mountain Songster are from the NGMS, so I assume the GMS is not indexed yet.

17 entries have Previous Source as GMS, all reprinted in other volumes. These are:

Joel Baker (4656)
Captain Ward and The Rainbow (224)
Charley's Escape (90)
Fair Damsel From London (180)
General Wolfe (961)
Jane Jenkins (731)
Johnny Scot (63)
The Labourer (19)
Lady Margaret and Sweet William (50)
The Shepherd's Son (11)
Sweet William's Ghost (50)
The Sailor's Bride (274)

(That's 12 songs - the others look like the same song printed in different places).

They are taken from Flander et al:NGMS; Flanders:Vermont Chap Book; Flanders+Brown:Vermont FS and Ballads; Flanders:Ancient Ballads Traditionally Sung in New England; Friedmann:Penguin Book of Folk Ballads;Frank:Jolly Sailors Bold

These are clearly not all the songs (they don't include some of the online ones), so unless someone comes up with a copy (or can get to a copy), there doesn't seem to be any more information available.


(Actually I can give you one more - The Jolly Thrasher No.92 in Notes and Sources for Folksongs of the Catskills: Supplement by Norman Cazden, Herbert Haufrecht, Norman Studer has a reference to NGS for version B)
