If you haven't heard Ewan MacColl, there are a large number of recordings available on CD, including the Radio Ballads (Sam Larner is also available). If you're interested call CAMSCO (800/548-FOLK) and I'll be happy to make suggestions.
Sadly, some of Ewan's major works are not available (yet?) on CD. I refer particularly to his LP set "The Long Harvest" )with Bert Lloyd, and "Blood and Roses" with Peggy Seeger. One cvan always hope.
