Here's Johnny Cash on the topic:
THE ONE ON THE RIGHT IS ON THE LEFT
Words and music by Jack Clement
As recorded by Johnny Cash on "Everybody Loves a Nut" (1966)
1. There once was a musical troupe,
A-pickin' singin' folk group.
They sang the mountain ballads
And the folk songs of our land.
They were long on musical ability.
Folks thought they would go far,
But political incompatibility
Led to their downfall.
CHORUS: Well, the one on the right was—on the left,
And the one in the middle was—on the right,
And the one on the left was—in the middle,
And the guy in the rear—was a Methodist.
2. This musical aggregation
Toured the entire nation,
Singing traditional ballads
And the folk songs of our land.
They performed with great virtuosity,
And soon they were the rage,
But political animosity
Prevailed upon the stage.
CHORUS: Well, the one on the right was—on the left,
And the one in the middle was—on the right,
And the one on the left was—in the middle,
And the guy in the rear—burned his driver's license.
3. When the curtain had ascended,
A hush fell on the crowd
As thousands there were gathered
To hear the folk songs of our land;
But they took their politics seriously,
And that night at the concert hall,
As the audience watched deliriously,
They had a free-for-all.
CHORUS: Well, the one on the right was—on the bottom,
And the one in the middle was—on the top,
And the one on the left got a—broken arm,
And the guy on his rear—said, "Oh, dear!"
4. Now, this should be a lesson:
If you plan to start a folk group,
Don't go mixin' politics
With the folk songs of our land;
Just work on harmony and diction,
Play your banjo well,
And if you have political convictions,
Keep 'em to yourself.
CHORUS: Now, the one on the left works in a bank,
And the one in the middle drives a truck,
And the one on the right's an all-night D.J.,
And the guy in the rear—got drafted.
