I'd love any poems that can be found. I remember that ubiquitous book of lyrics and poems he had at sessions.
I loved that poem that Liz has.
I was inspired to locate a book he bought me once because he thought I'd like it, and should read it: The Rubaiyat (an illustrated version) by Omar Khayyam. I'm not sure who turned him loose in an old book store, but I appreciate it.
