Today I am thoroughly exhausted so I won't write much!  The next artist is connected to Tim Buckley through a songwriter.  Buckley did an amazing cover of Fred Neil's song "Dolphins" for his album Sefronia.  The best version, one which won me over and made me a true fan of Buckley's is the live preformance he did in '74 on the British T.V. show Old Grey Whistle Test.  Harry Nilsson, and also did a cover of a Fred Neil song, "Everybody's Talkin'".  Nilsson achieved a lot of success in the 70s and is probably best known for his songs, "One", "Without You" and "Coconut" (whether you recognize the names or not you'll likely know all three songs).  The song "Everybody's Talkin'" was recorded for the soundtrack of the film Midnight Cowboy and is probably Neil's best known song.  So take a listen and look up Buckley's Old Grey Whistle Test version of "Dolphins" as well, both are songs worth knowing.
