Listening to the 1990 reissue of the album "Surrealistic Pillow" according to Jorma the name came for a comment by Jerry Garcia" about the music being "like a surrealistic pillow". Garcia on one reissue was listed as spiritual advisor (LSD Supplier is my guess). Great Marty Balin written song. Garcia is credited with guitar on this track. Garcia was around so much I feel because he saw a band with amazing potential, and he was doing Grace.
