There were only nine releases on Fight Back, catalogued FIGHT 1 - FIGHT 9.
Mortarhate Records and their distributor, Jungle Records, both list the Fight Back releases with Mortarhate (MORT) catalogue numbers in their discographies, but the MORT catalogue numbers are for internal use only.
No Fight Back Records release was released with a MORT catalogue number.
Quote from Jungle Records:
"Mortarhate catalogue numbers are sometimes given for internal purposes to other projects such as the Fight Back label, publications, and overseas releases."
