I found a photo with |gabbo| in it. I used it as the header to a new site destined to ferret out the little bugger.
Chop Smith, I included a link to your site as the official fan club location. I think we can find this guy. We're trying to locate archives of all of his advertising and any sighting information.

There's a tagboard so that people can list any sightings or leave info.
Thanks!
