Spoilers here. And some poor commentary of the acoustic sessions. Bear with my layman explanations.
Okay this is what I have: Lucifer's Hands is in fact Return of the Stingray Guitar with entirely new lyrics. No mention of the old lyrics at all. The main guitar part is prominent from the original song, though. "I can change the world, but I can't change the world in me," does feature, but the two clauses are broken apart by more lyrics in between.
The Crystal Ballroom is much better in its unremixed form, but this is a subjective view coming from someone that doesn't get into all that dancey remix stuff that they have done in the past.
The acoustic sessions are in fact one entire track. Begins with Every Breaking Wave, just Bono singing with a guitar. This is probably how I want to hear this version live, especially Bono's singing. Absolutely beautiful. Sometimes forget what his voice is still capable of doing. A violin joins in halfway through. I'm typing my immediate reactions as I'm listening and it's unreal how touching it is. At one point, Bono even loses his breath so it doesn't feel like a perfect rendition. Larry's cymbal comes in at the final chorus. Then his drums. As does Adam's bass. Ends too abruptly for me.
California is next. Again more stripped down, but I wouldn't call it acoustic as all four instruments are involved (I don't know what qualifies as acoustic. Don't like the foreign sound that comes in for the chorus. Sounds like a guitar but just... off, along with some horns. Not really feeling this version at all.
Raised By Wolves next, with Edge's acoustic guitar, omitting the percussive breathing effects and going right into Bono's lyrics, but still somehow including that punchy guitar sound after "I Don't Believe Anymore." Larry hitting some woodwind sticks together. Similar horn effect as in the acoustic California when they play the chorus. But Bono's singing sounds way more stripped down and enjoyable to listen to. High pitched keyboard still there, with Adam's bass.
Cedarwood Road next, with just Edge jamming on an acoustic. Edge backing vocals. New humming sound effect joins them. Still no sign of Larry or Adam this time. Bono's singing in fine form again.
Song For Someone next. Guitar sounds electronic to me. Light drumming from Larry and keyboards presumably from Edge. Singing is A1 again.
Ends with The Miracle (Of Joey Ramone). Acoustic guitar only and Edge joins on backing vocals for the oh oh oh parts. Sounds like Bono claps to the beat at parts too. Definitely clapping. No sign of Adam or Larry.
Not understanding the choice to have them as one track as it doesn't appear that they are actually playing them one after the other live.
The Troubles sounds very similar to the original. Lykke Li doesn't feature at all, Bono sings his main part as he originally did, but in a different style, and Angel Deradoorian sings backings. The chorus, "Somebody stepped inside your soul...," is different entirely, replaced with, "Somebody stopped the world I know. Somebody threw a line to me. Somebody tell me what to say." Not a bad version all up, though I don't like the new chorus lyrics, and ultimately I prefer the original because the band felt that was obviously the one that deserved to be on the A side.
Sleep like a Baby Tonight lyrics are 95% different, and all the same musical features are there; the haunting opening chords and the powerful guitar between chorus and verse, that harp, the piano keys, but it all just seems like there are a lot more instruments and noise in this one. I like the original much more because it comes across with the less is more mentality, and to me is more of a lullaby. Larry's drum hits sound A LOT like they do in Zoo Station, that very metallic sound effect.
And finally, Sleep Like a Baby Tonight goes for 11:06 because it does feature Invisible as a bonus track at the end. Baby Tonight goes for approx. 5:15 and then at 6:20, Invisible kicks in, making it 4:45 long (the Red Edit is 3:47). The intro is a bit longer, as is the bit just after that horn (?) sound starts. It actually feels slower than the Red version too, which might account for the extended track time, as there doesn't seem to be 1 minute of extra music. As such, I think Bono has resung this version to the new track speed, as opposed to just having slowed down his vocals along with the song. The bit between the first chorus and the second verse is twice as long. Again, I prefer the original because it has more urgency by not having those extra bits. The outro peters out for longer too. No new lyrics in this version.
