The Ash Grove (Welsh: Llwyn Onn) is a traditional Welsh folk song whose melody has been set to numerous sets of lyrics. The best-known version was written in English by Thomas Oliphant in the 19th century.
The first published version of the tune was in 1802 in "The Bardic Museum". The book was written by Edward Jones, a harpist. About 4 years later a version with words appeared, under the name "Llwyn Onn". It tells of a sailor's love for "Gwen of Llwyn". At the end of the song, Gwen dies, and in one version of the piece, the writer talks about him mourning and that she is lying " 'neath the shades of the lonely ash grove". The tune might be much older, as a similar tune appears in "The Beggar's Opera" by John Gay (1728), in the song "Cease Your Funning". In 1922, however Kidson claimed that John Gay's tune derives from the morris dance tune "Constant Billy", which is first known in Playford's "Dancing Master".
The first known version of "The Ash Grove" was published in 1862, in Volume I of "Welsh Melodies, With Welsh And English Poetry", authored by John Thomas the harpist, with Welsh words by John Jones (Talhaiarn) and English words by Thomas Oliphant. The first verse of this version is incorporated into Oxenford's version.
Down yonder green valley where streamlets meander,
When twilight is fading, I pensively rove,
Or at the bright noontide in solitude wander
Amid the dark shades of the lonely Ash grove.
'Twas there while the blackbird was joyfully singing,
I first met my dear one, the joy of my heart;
Around us for gladness the bluebells were ringing,
Ah! then little thought I how soon we should part.
Still grows the bright sunshine o'er valley and mountain,
Still warbles the blackbird his note from the tree;
Still trembles the moonbeam on streamlet and fountain,
But what are the beauties of nature to me.
With sorrow, deep sorrow, my bosom is laden,
All day I go mourning in search of my love.
Ye echoes, O tell me, where is the sweet maiden?
She sleeps 'neath the green turf down by the Ash grove.
