It still seems like an odd play for a track where the album version already seems tailor made to be a single, but it's growing on me. It's interesting that the Radio Mix contains an additional verse compared to the longer mix.
I do agree with you about MOFO; I have the Popmart Mix Radio Edit in my "U2 Singles" playlist. THAT was a hard promo to track down.
Now, this forum is a nice quiet little corner of U2 fandom, so I think that we can disagree without resorting to name calling. I don't think anyone was doubting the existence of this promo release; just opining over whether this should be the commercial single.
