Here are some great videos posted on Youtube by user gnrpdenver (a guy called AJ from Denver), who has been purging his VHS tape collection to rip videos of these great bands. The following CITIZENS ARREST footage is the only video I have seen of them, and it's a shame that they apparently split up shortly after this show, which Daryl describes as "a perfect example of our worst gig ever" over on Bid Hardcore. It looks like literally no-one is watching them. Still great though, and your mind will explode at 9 minutes 40 seconds in!
