Some fan-filmed footage has been posted online featuring shock-rock veterans Gwar from the D-Tox Rockfest in Quebec, Canada.  Check out the clips below.  Late last year, Gwar lost Cory Smoot, who has played the role of Flatus Maximus since 2002, as he passed away tragically in November.  The band retired the character, and is dedicating their current tour and next album to Smoot.
