1. Peggy-O

From the recording Peggy-O

"Peggy-O" is an old Scottish ballad.  It is sometimes called "Fennario" and probably derives from a ballad titled "The Bonnie Lass of Fyvie-O."  A wealth of interesting information about the song can be found in Josephine A. McQuail's essay "Folk Songs and Allusions to Folk Songs in the Repertoire of the Grateful Dead," http://www2.iath.virginia.edu/sixties/HTML_docs/Texts/Scholarly/McQuail_Dead_01.html
