I recently got The Oxford Book of Sea Songs ed. Roy Palmer out of the library - it's the 1986 edition. I'm aware that there's a revised and expanded edition entitled "Boxing the compass". I'm wondering if anybody's had the opportunities to compare the two editions, and would be able to tell me:

1) (and most importantly) What are the songs that Roy Palmer has added to Boxing the Compass that are NOT in The Oxford Book of Sea Songs? This review says "He has also added four relatively contemporary songs from the seventies and eighties, bringing the present total to 163" - so I'm basically wondering what those 4 songs are.

2) (less important, but interesting all the same if anybody wants to chip in on this) Are any other significant revisions that someone reading the older version of the book should know about?

Thanks in advance!
