3:25 is not the full length of "No Martyrs Cage", the copy circulating with that length is unfortumately cut short (rehearsal versions and modern recordings show the song to be over twice that length).
The shortened copy cuts out during the guitar solo after the first chorus of "Is this fantasy... Or insanity?", leaving the rest of the original studio recording sadly missing.
The cut-off copy was taken from the B Side of one of the original "Scheming Demons" cassettes, which were often loaded up with bonus material by the band, which varied between copies. A complete copy of this 3rd song from the original demo has yet to surface and circulate, although a 1982 rehearsal version and live recordings have been unearthed aside from the current bands renditions of the song.
