@jafani: If you don't already have it, the 1971 s/t Crazy Horse album (Reprise RS 6438) is fantastic! Danny Whitten was still alive and in the band, as was pianist Jack Nitzsche. Nils Lofgren plays guitar and sings lead on one song, and Ry Cooder plays slide guitar on three songs.
The album was issued in an expanded 2-CD package in 2005 (coupled with their second album Loose), entitled Scratchy: The Complete Reprise Recordings (Reprise/Rhino Handmade RHM2 7884).
