Finally paying attention to this song because of The Rescues' fantastic cover (featured in Pantheon), I noticed
(a) The current Wikipedia article is awful and could deeply benefit from better treatment but
(b) The previous version that included a Meaning section was just awful and patently wrong (a 1986 song wasn't focused on the fall of the Berlin Wall)
Given that this still comes in at the top of best Kiwi & Aussie songs ever, I'm curious if anyone here is enough of a fan to provide a solid foundation for understanding the song besides that it may be about a relationship and it seems to intend "Don't Dream [that] It's Over" instead of "Don't Dream [Because] It's Over".
