WHICH SIDE ARE YOU ON? (James Farmer)
Original verses by Florence Reece, new verses by James Farmer (CORE).

"I rewrote the old labor song by Florence Reece 'Which Side Are You On?' on the spur of the moment in the Hinds County Jail, after the Freedom Riders who were imprisoned there had been discussing and speculating about the attitude of local Negroes regarding the freedom Riders. We had learned through trustees in the jail that most local Negroes were with u, but afraid to do anything because of fear of reprisals. They told us that, of course, there were a lot of Uncle Toms around and it was hard to tell who was and who was not." -- James Farmer

Come all you freedom lovers, and listen while I tell
Of how the freedom riders came to Jackson to dwell.

CHORUS:
Oh, which side are you on, boys,
Which side are you on, (tell me)
Which side are you on, boys,
Which side are you on.

My daddy was a freedom fighter and I'm a freedom son
I'll stick right with this struggle until the battle's won.

Don't 'tom for Uncle Charlie', don't listen to his lies
'Cause black folks haven't got a chance until they organize.

They say in Hinds County, no neutrals have they met
You're either for the Freedom Ride or you 'tom' for Ross Barnett.

Oh people can you stand it, tell me how you can
Will you be an Uncle Tom or will you be a man?

Captain Ray will holler 'move on', but the Freedom Riders won't budge
They'll stand there in the ternimnals and even before the judge.
