Patient, diligent, and hyperfixated crowdsourced research has at last cracked the case: it’s “Subways of Your Mind” (1983), by German New Wave band FEX! https://www.reddit.com/r/TheMysteriousSong/comments/1gjbrs6/tms_is_found_the_song_is_called_subways_of_your/
Turns out that at least three of the band members (vocalist/lead guitarist Ture Rückwardt, keyboardist Michael Hädrich, and bassist Norbert Ziermann; drummer Hans-Reimer Sievers has yet to be heard from) are still alive and had had no inkling of their role in an enduring Internet mystery; it must have been like being accosted by a ragtag band of pirates who return the heirloom ring you left in a West German club restroom in 1984. On 4 November 2024, Hädrich provided a cleaned-up version…along with the other two songs on the original cassette EP.
Rückwardt, Ziermann, and Hädrich convened on 7 November 2024 for an acoustic reunion:
Update: Hans-Reimer Sievers, who seems to have withdrawn from music for some time, has come forward; he still owns his old drum kit and band tapes, and it looks as if a full reunion is imminent; dare we hope for new material?
