I also have another fan made Laser Squad themed mp3 called Assassin's Party, has anyone here heard it? I can't remember who it made it tho.
And finally here is Matt Furniss's original Amiga music courtesy of YouTube. (The title music plays for about 3 mins and then the in game music for the remaining 4:30). I don't know the situation with copyrights but it's worth a listen if you only ever played the 8-bit or the PC versions.
