Same, after I randomly got told that Heaven 17 were named after CWO, I had to check if the other fictional bands names were used by IRL bands.

Yea I loved the movie when I finally got to see it as a teen (IIRC it was banned in UK shortly after cinema release, lol, pussies), and I think I loved the novel even more (saw film first) because of how old it is, yet how strangely relevant it is today (major rises in youth violence, gang violence, rape, drugged up disillusioned teens, abject failure of the criminal justice system as usual, the disgusting looking council estate ghettos clearly designed to breed a generation of hateful violent youths etc, its almost prophetic ffs!). The other night my old man told me Heaven 17 were named after CWO, I cant remember why he said it but I knew I had to check to see if there were others too. Turns out there's also Johnny Zhivago! Anyway surely the novel & film are much more relevant now in the last 20 years than they were in the 50s and 1971 which shows how genius the whole thing is. Their fictional future London is just like modern day London and UK cities in general, minus the crazy gang outfits and judicial brainwashing programs!

Yes, seen them there but also at Benjamin's IIRC, though Playground X was more likely to be at Benjamin's and JZ or Monuments Galore would be at The Albert.
