Hump on your back and Bastard were originally released on "Dirty Love" It was most likely recorded during rehearsals for the Ace of Spades album.
Treat me Nice, Fun on the farm and You ain't gonna live forever were released on "Stone dead forever". The tracks on that CD are somewhat more scattered in time, it contains a version of Louie Louie as well as Fire Fire. My guess is that it's random outtakes from that period of time.
