The video you tagged is mine I filmed the show & that is my YouTube channel. The story of the glass is that one of the band, I think Ian, put a glass of water on the PA speaker and during the set it moved and fell off onto the stage. Guy thought someone had thrown it, there was a discussion with the crowd and this was explained to him.

As their very first European tour slowly draws to an end, Fugazi finds itself in Wigan, England. Both Ian's and Guy's voices are pretty much "sore and finished" by now, yet the band still manages to muster the energy to bust out another set.

Things pick up slowly as the band leisurely performs an instrumental while Ian addresses the peculiarity of the situation at hand, which seems to relate to the fact that only a handful of people came out of the woodwork to watch Fugazi play.

Band and audience never quite warm to each other on this particular occasion and things really hit rock bottom when Guy vents his frustration because someone appeared to have cut glass on his hat. If anything, it does result in a standout rendering of Burning.

Other highlights include Margin Walker, as it is one of the most coherent early versions I have heard so far, even though Guy's voice is a bit low in the mix at this point.

Not including the introductory jam, 14 songs get played, although it can be mentioned that Glueman cuts off untimely.

The sound quality of the recording is okay, plain and simple, not considering some nasty reverb and volume drops marring Lockdown.

A video of the show circulates on the internet (http://www.youtube.com/watch?v=7r4gaaq34HU). It showcases a good portion of the gig yet is disrupted after Turn Off Your Guns, which is actually the very last live performance of this song to date.
