Scarborough Fair is included under #2 in the Child cannon (The Elfin
Knight). Child (1882-1898)CPB also has this
variant. However, it is in the "Additions and Corrections" sections of
vol II
(pp495-496) and vol IV (p440).
Bronson (1959-1972)BTT also has this
variant
(vol I, p18). However, Bronson slightly alters the score, changing it
from a
3/4 to a 6/8 time signature. Bronson also makes a correction to the
text, changing "thine" in verse 4 to "mine".
According to Kidson, his copy, including the tune, used to be sung
by by a ballad singer in Whitby streets twenty or thirty years before
he published his volume, and was still remembered in the district.
Regarding the lyrics on the score, the lyrics are as set out in
Kidson's book. The lyrics do not quite match the words in the text.
Typesetting note - In Kidson's original score, the noteheads for the
two downward-stemmed minims (in the 3rd and 13th bars - partial bar is
bar 0) faced the 'wrong' way. I haven't been able to re-create this in
LilyPond.
