I was surprised not to find this in the DT or forum. Powerful stuff!

GREY OCTOBER (1966)
(C.Parker/Critics Group/P.Seeger)

Grey October in Glamorgan
High pitheaps where the houses stand
Fog in the valley, backshift ending
Children awaken in Aberfan

Warm October in Thi Binh Province
Huts of bamboo and rattan
Sun comes up - repair gangs stop
And children waken in Thuy Dan

Pithead hooter sounds from Merthyr
Load the coal in the waiting trams
Shoot the slag down the high pitheap
While children eat in Aberfan

Ox carts rattle down Thi Binh Highway
Work begins on the broken land
Night's work ended, the roadway's mended
Children eat in Thuy Dan

Dai Dan Evans grabs his satchel
Michael Jones his bread and jam
Five to nine and the school bell ringing
Time for school in Aberfan

School bell ringing, children running
Down by the river and across the dam
Hot sun burning, time for learning
Time for school in Thuy Dan

Lessons started in Pantglas Junior
Through the fog a black wave ran
Under the weight of the man-made mountain
Children die in Aberfan

Lessons start in the Thi Binh schoolhouse
And another day began
Bombers fly in the morning sky
And children die in Thuy Dan

Tears are shed for Glamorgan children
And the world mourns Aberfan
But who will weep for the murdered children
Under the rubble of Thuy Dan?

Grey October in Glamorgan
Warm October in Vietnam
Where children die while we stand by
And shake the killer by the hand

Note to song: 'This song was created by 16 people. The idea for it was conceived by Charles Parker, a BBC producer. Over a period of 6 weeks the song was shaped and re-shaped by members of the Critics Group and the tune was set to it by Peggy Seeger'.
