Rhymney (Welsh: Rhymni) is a town and a community located in the county borough of Caerphilly in south-east Wales, within the historic boundaries of Monmouthshire. Along with the villages of Pontlottyn, Fochriw, Abertysswg, Deri and New Tredegar, Rhymney is designated as the 'Upper Rhymney Valley' by the local Unitary Authority, Caerphilly County Borough Council. As a community, Rhymney includes the town of Rhymney, Pontlottyn, Abertysswg, Butetown and Twyncarno. Rhymney is known to many outside of Wales as a result of the song "The Bells of Rhymney", a musical adaptation of a poem by Idris Davies.

The town was founded with the establishment of the Union ironworks in 1801, with the Rhymney Iron Company later being founded from a merger between the Bute and Union Ironworks in 1837. The ironworks used local coking coal, iron ore and limestone. From the mid-19th century, steam coal pits were sunk to the south of the town. The ironworks closed in 1891 and by the early 20th century the town's collieries employed nearly the entire local population.

Peter "Pete" Seeger (born May 3, 1919) is an American folk singer and an iconic figure in the mid-20th-century American folk music revival. A fixture on nationwide radio in the 1940s, he also had a string of hit records during the early 1950s as a member of The Weavers, most notably their recording of Lead Belly's "Goodnight, Irene", which topped the charts for 13 weeks in 1950. Members of The Weavers were blacklisted during the McCarthy Era. In the 1960s, he re-emerged on the public scene as a prominent singer of protest music in support of international disarmament, civil rights, and environmental causes.

As a song writer, he is best known as the author or co-author of "Where Have All the Flowers Gone?", "If I Had a Hammer (The Hammer Song)", (composed with Lee Hays of The Weavers), and "Turn, Turn, Turn!", which have been recorded by many artists both in and outside the folk revival movement and are still sung throughout the world. "Flowers" was a hit recording for The Kingston Trio (1962); Marlene Dietrich, who recorded it in English, German and French (1962); and Johnny Rivers (1965). "If I Had a Hammer" was a hit for Peter, Paul & Mary (1962) and Trini Lopez (1963), while The Byrds popularized "Turn, Turn, Turn!" in the mid-1960s, as did Judy Collins in 1964, and The Seekers in 1966. Seeger was one of the folksingers most responsible for popularizing the spiritual "We Shall Overcome" (also recorded by Joan Baez and many other singer-activists) that became the acknowledged anthem of the 1960s American Civil Rights Movement, soon after folk singer and activist Guy Carawan introduced it at the founding meeting of the Student Nonviolent Coordinating Committee (SNCC) in 1960. In the PBS "American Masters" episode Pete Seeger: The Power of Song, Seeger states it was he who changed the lyric from the traditional "We will overcome" to the more singable "We shall overcome".
