Just to let you know that there is a Jaco's 60th anniversary issue of Bassiste (in French, bien sur): http://www.bassistemagazine.com/magazines/enkiosque.php
Not much new in it, though, but nice to have: An article about his songs, an article about the bass of doom and, interesting, an interview with Michel Hatzigeorgiou.
Best regards,
Philippe
PS this is a very nice photographic overview/clip about Jaco, on the music of Havona:
