WEEPING WILLOW TREE, THE. English, Morris Dance Tune (6/8 time). G Major. Standard tuning. A,A,ABABABAB. The melody was collected from the village of Headington, Oxfordshire, in England's Cotswolds, along with these words:

***

Oh, once they said my lips were red and now they're scarlet pale,
Oh, I was a silly girl to believe this flattering tale.
He vowed he'd never deceive me; I like a silly believed he,
The moon and the stars they shone so bright,
Over the willow tree.

(Quarry Men, c. 1950)

***

Oh, once they said my cheeks were red, but now they are drawn and pale,
When I like a silly girl believed his flattering tale.
He said he's never deceive me, and I like a silly believed he,
When the moon and the stars so brightly shone
Over the willow tree

(Journal, English Folk Dance & Song Society)
