I have a copy of this first U2 release from before they were signed. According to this page, I have the second pressing.
The sound is a more raw version of “Boy.” Interesting for collectors and fans, and I note from my Googling that the otherwise unpublished track (Boy/Girl) gets played in their shows pretty often. If you’ve seen them a few times, you may have heard it.
Wonder what else I’ll find?
More on how this not-so-rarity came to be here.
