One of my favorite bassist:

Not their best song but some real nice shots of Andy and his bass. I think it was on their What If album where instead of being listed as the bass player Andy is listed as Bass Innovator. :-)

Leprechaun Promenade; great tune!  It was originally on Night of the Living Dregs.

Maybe I should get a hobby and spend less time on youtube. Here is another great bassist playing a great bass -
Tom Fowler
With Frank Zappa 1974.
