I haven't seen/heard it yet, but the two buddies are Guy Clark and Steve Earle. Guy Clark was talking about it with the Mike Regenstreif on Folk Roots/folk Branches last Thursday.

There is also another "new" one called "Texas Rain," an album of duets with Townes and a bunch of others. As I said in an earlier post, Mike played the version of "Pancho & Lefty" from it with Freddy Fender.
