It's a logical thing to think - U2 does things in threes (I will someday finish that post analyzing their album releases - it's more than just threes...) Bono tends to think out loud in interviews (i.e., the things he says about the future are merely on his mind - whether or not they actually come to pass is a different thing altogether) - I do remember his saying "Songs Of Ascent" in an interview, but that was back during the NLOTH sessions, and, after I did a little research, I noticed that "Songs Of Ascent" was one of the working titles for NLOTH. I think I posted that earlier.
For better or worse, I do think their next CD will be a "best of" or a live album (perhaps of the JT tour, perhaps something else). If they did another "best of", they'll put something new on it. I just hope it's more than one song. Yes, I can't wait for their relationship with Live Nation to end - I hope it does. (Just because we want it doesn't mean it will happen, though.)
"Drowning Man" and "Like A Song" are both songs that have never/virtually never been played. However, being a big fan of "War" myself, I'd also be up for it! (It's my favorite album of theirs from the 80s.) Here's a list of songs they have not played:
All will be revealed about the SOE concerts very soon now! ?
