The lyrics, from memory (and therefore likely quite wrong in places):

The bird of freedom has a golden wing
And brotherhood is a commercial thing
All you really need is a guitar
That's all you really need to be a star
The wind of change is on the way
The sound of protest has begun to pay

Tell them about the dream you had last night
How every politician saw the light
But keep those dollar bills way out of sight
Because a well-dressed rebel don't look right

Some rebels are commercial, some are not
Some rebels make a million, some get shot
If a halo isn't worth the risk
Why not settle for a golden disk?
The wind of change is on the way
The sound of protest has begun to pay

Great stuff. And they did a passable impression of the Byrds, didn't they? but I don't recall the Byrds doing a whole lot of protest songs (unless you count Chimes of Freedom) so I don't really see where the song would have caused them much distress. Trivia buffs will know the other Trio-Byrds connection; Roger McGuinn, when he was Jim, before the Byrds, played on some of the early Trio albums.

I think the Trio did a lot more protest material than the Byrds ever did, and I don't know whether any of them ever put himself in a position to be shot - then again, I don't know that they ever made a million, either - I think I had a point to make when I started this, but the two remaining neurons are still trying to recover from the effort of dredging those lyrics up out of the murk. Great stuff, and much better on vinyl than on your monitor.
