One of my favorite bassist:
Andy West (http://www.youtube.com/watch?v=VNWEbRnAmb4)
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 (http://www.youtube.com/watch?v=LszJ9sM3bbk&feature=related)
With Frank Zappa 1974.
