Here are some more:

2225)  THE MAGPIE 2
Though the DT file does not say so, this was noted by Peter Kennedy and S. O'Boyle from Annie Jane Kelly at Keady, Armagh, in 1952, as The Magpie's Nest.  The tune is a variant of The Cuckoo's Nest, as the DT file does, rather obliquely, suggest.  Midi made from notation in Kennedy's Folk Songs of Britain and Ireland, 1975.

2143)  LONESOME DOVE 3
Noted by Cecil Sharp from Mrs. Ellie Johnson at Hot Springs, N.C., in 1916, as stated in the DT file.  Midi made from the notation in English Folk Songs from the Southern Appalachians (Oxford University Press, 1952).

2228)  MAID AND THE ROBBER
DT #419, Laws L3 (The Undaunted Female).  The DT text is from Gavin Greig.  Two differing tunes and one text are given in The Greig-Duncan Folk Song Collection, vol. II, p.286, and I have made midis from both sets of notation.  The first is from an unnamed source; the second (and possibly the text, also traditionally called Box on Her Head) from a Mrs. Strachan, c. 1908.  Mrs. Strachan sang a refrain, not given in the DT: Wi my fal de do i di-do, fal-al-de-da.

1100)  THE FARMER FEEDS THEM ALL
And thread  HELP-origin of THE FARMER IS THE MAN?  where I have posted the original text as written by Knowles Shaw, c.1870s.
Midi -melody line only- made from notation in The Century of Song, vol. II, comp. Adam Geibal (Philadelphia, 1897).  The chorus is arranged for four voices; I've used the soprano part as most closely resembling the tune as now sung.

2496)  NO CHURCHMAN AM I  Lyric by Robert Burns.  The tune is Prepare, my dear Brethren, to the tavern let's fly; midi made from notation in James Kinsley, Burns: Poems and Songs (OUP, 1969).  In the fourth line of the first stanza, "business" is given one syllable only.

2616)  THE OLD MAN'S TALE   Properly called The Old Man's Song; written by Ian Campbell and set to the tune of Nicky Tams.  Midi made from notation in The Big Red Songbook (Pluto Press, 1977).

2805)  THE POSIE  Lyric by Robert Burns (as specified by Alice, who posted it), though the DT file makes no mention of this.  Midi made from notation in James Kinsley, Burns: Poems and Songs (OUP, 1969); I have put in a form of trill in the final bar where one is indicated, but with no guarantees that it's an historically correct one.

2839)  THE PRODIGAL'S RESOLUTION  From D'Urfey's Wit and Mirth: or Pills to Purge Melancholy (1719-1720).  The tune is Jamaica, also given in Playford's Dancing Master, edition of 1670.  Midi made from Playford's notation, as reproduced in Simpson's The British Broadside and Its Music (1966).

2843)  PROUD LADY MARGARET  Though the DT file does not say so, this partial text is from Gavin Greig's prolific source Bell Robertson (1914); she learnt it at the age of about 14.  Miss Robertson did not sing, so there is no tune recorded.  The Greig-Duncan Folk Song Collection (vol. II, 1983), however, gives another, fragmentary text, with tune, which was noted from a Mrs. Gordon of New Deer, Aberdeenshire, in 1904.  While there is no evidence that the Robertson set was ever sung to this particular tune, the two were found in the same locality only a few years apart, so this is probably the closest we will get.  Midi made from the notation in Greig-Duncan.

3249)  SPRING GLEE  This is the Copper Family's When Spring Comes In, filed under an unusual title.  Midi made from notation in Bob Copper's A Song for Every Season (1971).

3270)  STORMY WINDS  The DT file describes this as "from the singing of the Copper Family", which is code for "learned from a record".  As it happens, I'm not aware of this song ever having been in the Coppers' repertoire; the text given is that recorded by the Watersons, and I suspect a mistake in ascription.  The tune used was noted by H. Balfour Gardiner, from Benjamin Arnold, of Easton, near Winchester, in 1906; the text is a collation of Arnold's and another, noted "from the stationmaster at Cliddesden, near Basingstoke, Hampshire" by George B. Gardiner in 1907.  Midi made from notation of Mr. Arnold's singing in The Journal of the Folk Song Society vol. III, issue 13, 1909.  A number of variations were also noted, which I have not incorporated.  If I recall correctly, the Watersons changed the tune a bit, but trying to notate their singing can be a pain sometimes, and I don't feel like doing it.

There are some mistakes in the DT file.  In verse 3, line 1, mount or plain should be Mount Star plain; in line 2, did weave should be did bleat.  In verse 5, line 1, grimy should be rimy; in line 3, hail or, though logical, is not what the Watersons sang; they followed the unnamed Stationmaster in singing ilgo, whatever that might be!  It's also worth mentioning that the Watersons changed Mr. Arnold's ready to complete (verse 2 line 2) to the more sensible ready to bleat, as given in the DT.

Note:  There is another version in the DT,  SHEPHERD'S SONG;  a tune is given, but no source is acknowledged.  As it happens, it's the set sent to Lucy Broadwood by F. Scarlett Potter of Halford, Shipton-on-Stour, and published in English County Songs (L.E. Broadwood and J.A. Fuller Maitland, 1893).  "The first verse was taken from the recitation of a lady born at Stoke, Gloucestershire, in 1793; the remaining verses were recovered from Thomas Coldicote, shepherd, of Ebrington, Gloucestershire.  Blockley, referred to in verse 3, is in the parish adjoining Ebrington."

3441)  THREE SISTERS  This fragment of Babylon is given in Bronson (Traditional Tunes of the Child Ballads, vol. I) as number#14, example 6; Doon by the Bonnie Banks o' Airdrie, O.  Midi from the notation in that book.

NOTES:

3104)  SEVEN DAFFODILLS  This is a mis-spelled duplicate of  3105)  SEVEN DAFFODILS ,  and probably needs to be deleted.  The song is a modern one, written by Lee Hayes and Fran Moseley in the early 1960s.  I have no idea what the tune might be.

3150)  THE SINGLE BOLINDER  A modern song, based on  LITTLE CHANCE  and sharing its tune, which I've already sent to Alan.

3231)  SONG OF THE THE GILLIE MORE  [sic] This is a duplicate, with the title mis-spelled, of  GILLIE MOR,  for which the tune (a slowed-down Whistle O'er the Lave O't) has apparantly already been supplied.  The former file should probably be deleted.

3310)  THE SWEET FORGET-ME-NOT  This is a duplicate, slightly more accurately transcribed, of  (3309)   SWEET FORGET-ME-NOT,  for which a tune has apparantly been supplied.  Both texts appear to have been transcribed from a recording by Ian Robb.  3309, as the (marginally) inferior duplicate, is an obvious candidate for deletion.

1792)  ISLAND OF BOTHIES  This is an English translation of a set of  FIONNGHUALA,  for which I have provided a (rather oddly-notated) traditional tune.  It might be sensible to combine the files, or at the very least cross-reference them.
