"Jack an' Joe", also known as "Give My Love to Nellie" and "Jack, Joe, and Nell" is an American song. It is in the Missouri State Max Hunter Folk Song Collection, sung by Ollie Gilbert, Mountain View, Arkansas on February 9, 1970.
This seems to be an instance of a music-hall production establishing itself as traditional song. It is reported in tradiion from Kentucky (Shearin 24), Tennessee (JAFL xliv iio-ii, SSSA 135, FSSH 173-4), Mississippi (JAFL xxxix 160-1), Florida (FSF 64) and Illinois (TSSI 244-5). The Archive of American Folk Song lists records of it from New York (B. L. Lunsford), Arkansas and Wisconsin.
The melody is very close to "Danville Girl".
"Two Little Lads" is a variant. Along with "Joe Bowers" it is one of the family of "the girl I left behind" songs where the girl marries someone else while her lover is away.
It was recorded by John A. Bivens on Hand-Me-Down Music: Old Songs, Old Friends - Vol. 1 Traditional Music of Union County, North Carolina (1979).
It was printed in Abrahams & Foss' Anglo-American Folksong Style (1968), the Monroe (Union County) Journal, November, 1916 and The Frank C. Brown Collection of North Carolina Folklore: Volume 2 - Folk Ballads (1952).
