I always think of the great Civil Rights anthems as being We Shall Overcome, Ain't Gonna Let Nobody Turn Me 'Round, and Keep Your Eyes on the Prize. One mild, one militant, and one, Eyes on the Prize, outright confrontational (its my fav, can't you tell). Kumbya and MRTBA are more relics of the long forgotten "Folk Mass" movement that started in the Catholic Church (They had more nuns running around with guitars) and eventually spread to other faith groups. Judaism was a bit different in that a lot of the religious songs are also folk songs in the first place. You were far more likely to hear Kumbya and Michael at some campfire, at some vaguely religious type summer camp then at a Civil Rights Rally rally.
I know that because I was a student at schools with all those nuns running around and Sister Whatawaste with her guitar (and as I have come to understand in some measure of compassion, a major problem relating to men and boys) trying to make the whole god deal it 'relevant' to us young people in the space age scientific age and its rock and roll soundtrack. I'll give them points for trying at least, but by the time Sister Whatawaste got out her guitar and tried to teach us groovy folk songs from Africa we had already moved into Jimi Hendrix and the Beatles' White Album. It just sounded lame. Largely, because it was.
I know about the Civil Rights stuff because as Michael Savage would have it, I'm a Red-Diaper Doper Baby. My mom was involved in all that stuff, anti-war, anti-nuke, pro Civil Rights big time, and I got hauled to rallies in the mid and early 60s, from the time I was about 7 or so. Though with mom it was always that Dorthy Day type DEEP Catholic social justice deal, and not a political statement. My mom lived a high suburban lifestyle complete with Caddy, a less socialist/commie type would be hard to find. At any rate, I remember a lot of that stuff - indeed its very hard to forget, it was very powerful. To say the least. So I can still hear those voices singing
The only thing I did was wrong
Was stayin' in the wilderness too long
Keep your eyes on the prize, Hold on
Only thing we did was right
Was the day we started to fight!
Keep your eyes on the prize, Hold on
And that's a long way from Kumbya. Though there is a weird tie in having to do with the kids who went down south to do Freedom Summer and all coming back to their preppy East Coast schools with Odetta records.
And the reason I'm not the person to ask is that my opinion is not going to be very helpful to most people. I don't see what they really want described. And I'm looking at it from a different vantage point, and running it through a very different set of background filters. I've worked 30+ years on show, some of the biggest, and at all the great venues, I've worked and toured with huge acts, and lot of stuff that no one remembers, I've done (more or less) 200+ shows a year while working. So, that's a lot of bands. And, I don't see the show from the same place. I'm hiding in the wings, watching and hearing something very different. Or I'm in the booth running a board or a spotlight.
And yes, I've seen RyG several times live. A band, not a bad one either, called Gomez was headlining the Warfield, and saw them playing in the Haight at a record store and brought them in. So we are setting them up, and they are playing - like inches from us as we worked around them at the last minute, and all of our eyes got big. When they did their set, I actually went up into the hall to watch them, and so did everyone else. That like never happens.
