Steve Earle: Steve's Hammer (for Pete Seger):
Eric Bogle - A Reason For It All - LIVE small gig (written by Bogle)
Rusted Root - Ecstasy with excellent video
(see youtube for video)
Buddy Guy with Angelique Kidjo - Voodoo Child from documentary Blues in a Bottle LIVE
The Smothers Brothers LIVE - My Old Man skit and song combination
(Their show got canceled because of song/skits like this; they thought it was worth it, and really couldn't have done it any other way.)
Most of these songs are what some would call political; all of them are life-enhancing in the sense of truth telling, questioning status quo, taking a stand of one sort or another.
At my age, I have hundreds of "get it up" songs; here are just a few favorites.
I tried to copy/paste from the thread with all songs LIVE but for blogging I found out I could only choose one. Hard call, but I made it Eric Bogle's because of all the songs this is the kind of song to make anyone the least bit in touch with paradox do some thinking.
