If you have a lot of patience you may be able to reconstruct Ten of Swords from the official Dylan bootleg series releases / youtube videos. http://forums.stevehoffman.tv/threads/r ... es.231350/
Here's a copy of the booklet that came with Ten of Swords to get an idea of where all the songs came from:http://www.bobsboots.com/swords.html
If he doesn't have them yet you might be better off just buying some of the official bootleg albums (especially if you can find the Deluxe edition ones). If he does have all that stuff then he's already reclaimed a good chunk of Ten of Swords...
Hopefully someone out there has a copy for nostalgia's sake / Good luck in your search.
