Ray Lamontagne music party

I'm trying to host a "Ray Lamontagne Party" listening to all of his albums. Unfortunately I only have the big 4. Any idea where to get Green Demo, One Lonesome Saddle, Raycharles LaMontagne demo,Acre of Land or any other of his hard to get albums? Purchase, exchange, download, anything.

It's hard to have a party and only have the four albums available at the library.
