Wasn't this a smaller street show as well in San Marco around 2008 or 2009 for a season or two? Just three guys out on the street in the open area between the food lines and the seating, doing the stomp type stuff and the cleaver/knife percussion stunts?
I remember catching them a few times but they weren't on the programs I don't think. I didn't go to the park from 2000-2002, so I missed the full show on the stage, but I really liked it as a street show, too.
