You haven't found it anywhere because it isn't an official release. It was taped off a broadcast and people have been swaping it in video form since then.
What format are you looking for - tapes (VHS or Beta or something else), mpeg (on CDR), VCD (NTSC or PAL or doesn't matter), DVDR (NTSC or PAL or doesn't matter, DVD-R or DVD+R or doesn't matter)...?
