As apparently was true for others, NYD was my #1 U2 song when I first became a fan and remained so for many years. The studio closing is a great ending, and I used to consider it indispensable to the song; I couldn't understand why the band changed it live. Only years later did I discover that the live versions follow the single edit. Over the years, I have come to believe that the melancholic studio ending, while provocative and worthwhile in that context, wouldn't work as well live. The band made the right choice for both the single (as the downbeat ending might have hurt airplay/single sales) and live, IMHO.
