Pmack> OK, look, this is the Real Deal here. I have nothing to do with that lame ass Zwanphoria
Pmack> That Spiteface clip is from the 1989 video; the date is unknown because the whole tape is full of assorted clips.
Pmack> This 1989 video is also the source of the unknwn She that's circulating, as well as the My Dahlia rehearsal.
Pmack> Also the source of 10.31.89
Pmack> I bought it from a girl who was close to the band in 1989. This girl is also the source of the "Ignoffo Tape".
