The Bells of Rhymney is based on a poem by Welsh coal miner and author Idris Davies. American folk singer Pete Seeger turned the poem, originally titled Gwalia Deserta, into a song. Davis wrote that the poem was inspired by two major events in the Welsh coalfields: The Senghenydd disaster, and the 1926 general strike. The lyrics highlight the difficult and dangerous conditions that faced Welsh miners during the early twentieth century.
The Byrds made the song into a folk rock hit in 1965. Scroll down to compare their version with the original version from Pete Seeger and a version from The Alarm, a group from Wales during the 1980s
