I have the Folkways LP, including the jacket, which however has no information on it, and an insert, which explains a good deal. According to it, Allison did not write any of the songs, and only two are of known authorship. However, he "had recourse to expansion or contraction wherever it seemed necessary".

In particular, the one called "Flud Ireson" is an abridgement of John Greenleaf Whittier's poem "Skipper Ireson's Ride", which (as noted there and elsewhere) is widely held to be inaccurate & unfair not only to Mr Ireson, but to the women of Marblehead.
