Ken,
Yup.  Most likely Trevor's bass.  Third paragraph up from the bottom lists Trevor having an Alembic:

three basses (an Alembic, an Aria Pro 1000 and a Fender Jazz with a Precision neck)...
John

You nailed it.  It was Lequient Jobe.  Thanks for the refresher.

Keavin, check this one out of J. J.'s son...
 

Is that his son? i thought that was james in a later photo.

Guitar Player magazine did an extended piece on Jamerson not too long before his death.  Pictures, too.  Anybody got that one?
John

Keavin,
 
It's J. J.'s second son, Joey.
 
Darrell

One has to wonder what kind of pressure the Jamerson kids are under to be great bassists like their dad.  What a heavy, heavy torch to carry.  I hope they're happy doing it.  Anybody ever hear them play?
John

James Jamerson Jr has a whole bushel-load of credits on pop and R&B recordings in the 80's and 90's.  Although I can't think of any specific tunes right now, there were some pretty popular songs and groups in his discography.  He's also heard on some of the recordings on the Standing In The Shadows collection / tribute to his father.
 
Peace,
 
James

  I could not leave Mr. Verdine White excluded...  

Okay, I am sorry, but how could Mr. Geddy Lee not be included in that list?  Sure, he doesn't play Alembics, but his sound and style have influenced almost every newcomer in the rock genre for 20 years!  Also, he is the main reason I learned to play bass.  Say what you want about RUSH and their music and his voice, but hands down he is one of the most versatile players there is.
 
Also, I could never think of leaving off Chris Squire too!  And what about Mr. Dependable, Tony Levin?

Okay, here you go...
 

I think we forgot to mention (in my humble opinion)the father of the Cool upright  - Charles Mingus!
 
I still draw an enormous amount of inspiration to go fretless each time I listen to him.  Even his simple walking Bass lines are cool.  His orchestral stuff is really awesome as well.
 
Charles Mingus - the musician's musician (Who happens to play a mean upright!).

Rami,
It seems like some people's appreciation for music just doesn't go back any further than what came along after 1960.
Yesterday I was checking out the Branford Marsalis recording of Coltrane's 1964 A Love Supreme suite. It's on DVD+CD - the DVD is supposed to be the hippest live jazz DVD out there, but the shop could only play me the CD and that was pretty hot in itself. Bass player by the name of Eric Revis, and the band as a whole really was playing its *ss off.
Now where's that East Coasting CD?
