Sir, I think that "A Tribute to Woody Guthrie" album is still available on CD from Warner Brothers. If I'm reading it correctly, it's #9 26036-2. I got mine from the BMG CD Club. Don't know if BMG still carries it - they don't seem to keep folk CD's on hand for very long. It certainly is a great album. Arlo's recording of "Oklahoma Hills" is my favorite cut on the album, I think.
