So sorry I did not answer this sooner. I just recently checked this listserv, having forgotten about it while in the midst of writing on Kane. As Malmo58 says, Kane did not want her productions videotaped because she felt that to do so would undermine the fact that her plays were written for theatre and that there was something specific to witnessing them as produced in theatre that contributed to one's reaction/reception of the plays. She seemed to be consistent in this bias, believing in the power of live theatre and rejecting other means (particularly video) to reproduce that which occurred when her plays were produced in the theatre. I don't have the reference in front of me, but I do remember reading this in the files on Kane over at the V&A Theatre and Performance Archive. Of course, Kane's allergy to having her play's videotaped may frustrate researchers (though the V&A archive does have several photos and blue prints of sets, etc), but there is something about this sentiment that I find consistent to Kane's work. Consequently, I appreciate her decision, even if it means the closest things I have to seeing the world premier of a Kane play are photocopies of very small positives.
