The radio ballad is an audio documentary format created by Ewan MacColl, Peggy Seeger, and Charles Parker in 1958. It combines four elements of sound: songs, instrumental music, sound effects, and, most importantly, the recorded voices of those who are the subjects of the documentary. The latter element was revolutionary; previous radio documentaries had used either professional voice actors or prepared scripts.
Original radio ballads.
The original radio ballads were recorded for the BBC. MacColl wrote a variety of songs especially for them, many of which have become folk classics. The trio together made eight radio ballads between 1958 and 1964. They were: 
"Singing the Fishing" won the Prix Italia for radio documentary in October 1960. All eight radio ballads were released on LP, by Argo Records, and later on CD. They are also available via Listen Again on 
the BBC Radio 2 website.
A book about the making of the radio ballads was published on the fiftieth anniversary of the first broadcast of "John Axon". "Set into Song: Ewan MacColl, Charles Parker and the Radio Ballads" was written and researched by Peter Cox, published by Labatie Books and has an extensive website which carries the first two pages of each chapter, the complete transcripts and cast lists for each programme, bibliography, footnotes and reviews.
Missing ballads.
In an unpublished letter to "The Guardian", in 1999, Ian Campbell detailed a further two programmes made a year apart, by Parker, with music by Campbell (and John Chapman in the former case), without the involvement of MacColl or Seeger, and broadcast, according to Campbell, "to critical acclaim", then "consigned… to permanent oblivion".
2006 radio ballads.
In 2006, BBC Radio 2 broadcast six new radio ballads using the same format, with musical direction by John Tams, and contributions from Karine Polwart, Jez Lowe and Cara Dillon among others.
