I checked Folk-Legacy and found nothing. At CDNOW I did a search using the "song title" option in the search box. I found several recordings, but none that appeared to be choral. Unfortunately, I don't think CAMSCO has a song-by-song listing of its inventory. Seems like several collections have the Ewan MacColl recording.
If you click here to search CDDB, you'll find a list of 44 CD's that may have the song.
I see that the Glasgow Phoenix Choir has a recording - I wonder if this link (click) will take you to all of their recordings of the song.
If you'll settle for smaller male groups, try these:

• A group called Men of Worth have it on their "In Full Flight" album
• A group called Schooner Fare have it on a couple of CD's.
