It's obviously not Carol Jantsch; you can see the gentleman playing the tuba solo on the video at 7:49.

Is it Steve Dumaine, Craig Knox, Ed Diefes, or someone else?

It's Ed Diefes. That concert is from 2005 however.

D'oh! I was looking at the date that the video was posted on YouTube, not the description that included the 2005 performance date. Thanks for pointing that out, Andy.
