The BBC has commissioned Wales' former national poet, Gwyneth Lewis, to write a poem about the Gleision Colliery mining tragedy.
Philip Hill, Garry Jenkins, David Powell and Charles Breslin died when the Swansea Valley mine flooded last week.
Ms Lewis read the poem on Radio Wales' Good Morning Wales.
