G'day yet again,I should check the DT more carefully: it is there under a slight variant spelling )(Manyura Manyah?) and thus didn't show up to a direct search on Pete Seeger's spelling.
This one has (presumably) more authentic Braid Scots, Glasgow version, and has a copyright date of 1964 ... which is not exactly what is suggested by the Seeger recording, but perhaps he did not copyright immediately.
Regard(les)s,
