There is a collection (7CDs) entitled "Ewan MacColl & Peggy Seeger Original Songs 1932 -1988" which includes the Radio Ballad songs and these have been reversed engineered so that actuality from the radio ballad that sometimes split the songs up has been removed, and what is left is only the song sung by the original radio ballad singers.

Makes for interesting listening - as does the rest of the material in the collection of some 160 tracks
