The Gum Tree Canoe," sung by Frank Crumit as posted above by Frank Maher, is identical to the version in Randolph, Ozark Folksongs, vol. 4, p. 302 (new ed.), # 787.
There are two versions in the Max Hunter Collection.

The song was printed in "Heart Songs, 1909, p. 250, as "Tom-Big-Bee River," by S. S. Steele, four verses and chorus ("Singing row away, row..."). The song is printed in minstrel dialect.

The version posted by Bill at the start of the thread has had the dialect of the early versions removed, so its blackface origin is not as apparent.
