I do have a video of an audience recording of the band playing at the 1991 Reading Festival. Got it from an eBay seller back in January 2003, and I've never seen another copy anywhere else. I also have a couple of MTV interview clips from after the gig with Andy & Stephen. I think Andy said that performing a gig in broad daylight was highly unusual for them.
I also have another VHS tape from another gig (Slowdive & Chapterhouse). It's pretty dark, but I'm a fan, so I got it anyway.
I could be open to trading/sharing/whatever. Also, I will be at the Chicago gig on October 1st if anyone wants to meet up.
