If they were to ever do a full acoustic show, I hope they would do what Pain of Salvation did and heavily rework a lot of their songs into completely new versions. To be honest, i suspect that would be the only way that it would fully work. Done right, When They Come For Me would be amazing.
It could be cool. That's kind of what we've gotten with the summits and such. Maybe just some videos on YT like Young The Giant does for their songs, that way they can make sure to get it right and such.
Have a look around YouTube for acoustic versions of LP stuff....Why, here's some blokes from Australia-land doing Papercut. Goes alright, I reckon. Hand it over to LP and you'd be laughing. [video=youtube;CYgtWWlUNng]http://www.youtube.com/watch?v=CYgtWWlUNng[/video]
