"Peace Must Come," which contains the line, "over and over again," is New Zealander Paul Metsers' song, not "an Englishwoman whom Bob Walser met/knows," according to Priscilla Herdman, who recorded it.

From http://folksong.org.nz/fwltgold/index.html:

"For years we have sung along to such New Zealand folk standards as Farewell To The Gold, People I Want To Be, The Seal Children, The Swag and the Shiner, and Peace Must Come, without perhaps realizing they were all Paul's work."
