Meanwhile in 1957, a U.K. film company, Data Film Productions, had filmed Ewan MacColl, assisted by Cameron and others, singing a number of songs about coal mining for the National Coal Board, illustrating them with "little proto-pop-promos featuring local people in the relevant regions as their casts" (it is not clear how many feature Cameron). Under the name "Songs of the Coalfields", these were released as six separate stories in episodes of "Mining Review" (a monthly newsreel "magazine" for the coal industry and mining communities) and later (1964) combined as a single 16mm film, available in the British Film Institute archive. She also participated in the recording of three of Ewan MacColl & Peggy Seeger's "Radio Ballads", entitled "The Ballad of John Axon" (1959), "Song of a Road" (1959) and "The Big Hewer" (1961), later released on LP in 1965 and 1967 although "Song of a Road" was not issued until 1999.
