Her's a pic of the Rev standing on top of Jimbo's Bass - Jimbo's there, too. Down low.
(link to a 1024 above)
Here's another "shot":
Now here's a mystery explained: I always thought that the Rev was portraying a chicken (possibly a guinea hen) antagonizing an insect, child, or other barnyard animal (as portrayed by Jimbo) in the following clip:
But then he explained that after playing Atlantic City the night before and crossing the mighty Delaware on his way to Philadelphia, his pathological fear of Bottlenose Dolphin was reawakened. I now get it- predatory swimming and a sinister dolphin cackle on guitar - it's not a chicken at all - it's a dolphin attacking a swimmer!!!!
Luckily that huge Bass makes a great flotation device......
