Gwalia Deserta was a cycle of poems about the Depression, and the bitterness and hopelessness it engendered; The Bells Of Rhymney was a part of that.

But Idris Davies shall be remembered for his incisiveness of his poems and his love for the Valleys of South Wales. On their album "Songs And Tunes From South Wales", Calennig recorded the poem "When April Came To Rhymney":

When April came to Rhymney
In shower and sun and shower
The green hills and the brown hills
Could sport some happy flower
And sweet it was to fancy
That even the blackest mound
Was proud of its single daisy
Rooted in bitter ground.

And old men would remember
and young men would be vain
and the hawthorn by the pithead
Would blossom in the rain
and the blackest streets of evening
They had their magic hour
When April came to Rhymney
In shower and sun and shower.
