Concerning how easy / difficult it is to get your hands on these tracks:
ANDROID
B-Side of What Evil Lurks [except Netherlands, there it´s A-Side] - I must admit I searched for ages for a copy of "What Evil Lurks" from 1993 - 2003. It seems to be impossible gettin your hands on it until there was the Re-Release of it in 2004 which seems to have lot more copies than the original one from 1991 - not hard to find item today IMO
Also track on the "Experience-Expanded" Compilation
BABY´S GOT A TEMPER
C´mon - this is a joke, isn´t it ?
CRAZY MAN
B-Side of "Everybody In The Place" Single, still easy available in every good store and internet-shop. It´s easier to get it than "Rip Up The Sound System" which only was on the vinyl or the first release of the CD in 1991
DESERT
As far as I can remember it was the Beta of "Medusas Path"
G-FORCE
Got this tune first time on "Only For The Headstrong" Sampler and later on the re-release of "Charly" single - not hard to find track today
