ACLU Version of 'Peacekeeper'...

[The Nisse]

Hello...

I just downloaded this song from Nancy's web page (great site btw!) and I ask the question: What is this...?
It sounds like Lindsey doing the song on his own with only his vocals and synth-drums. Could it possibly be what he intended for the Gift of Screws-album...? I must say prefer the FM, Stevie's vocals really make a difference...
Finally, what does "ACLU" stand for...?

Please help me out here. I kinda get the idea it's a dumb question, but I'm a newbie...!

Michael..
