There is now a Guy Fieri Road Show YouTube channel.
In the upper right hand square of the page, you'll see the three most recent uploads; click on see all, to see all of the clips that have been uploaded.
At the time of this writing, there are fourteen clips of backstage, behind-the-scenes footage, and some Guy Fieri Road Show video from the performances with DJ Cobra, Woody (flair bartender), Stretch (from Grinders Pizza in Kansas City, Missouri - episode) and Panini Pete (from Panini Pete's Cafe and Bakeshoppe in Fairhope, Alabama - episode) and various tour crew and fans. Here are a couple of my favorites:
