We think Sister Ray comes from this gig. What there is is a distorted and rather short version of Sister Ray that starts off with Bernard making some comments about the security I think (memory's a bit hazy these days) and the song gets truncated after about two minutes, as though something's happened on stage.
What we do know is that at one of the Tokyo 85 shows, after the band did an encore they left the stage and the stage lights came up, the crowd left and the security escorted them to the venue doors. Then the band came back on to do Sister Ray and there was a stampede, and the performance was cut short as all hell had broken loose. We've never been sure which date it belongs to, and the sound quality is crap, but it did happen and does exist.
