MacBird! is a 1967 satire by Barbara Garson that superimposed the transferral of power following the Kennedy assassination onto the plot of Shakespeare's Macbeth.
Thus John F. Kennedy becomes "Ken O'Dunc", Lyndon Johnson becomes "MacBird", Lady Bird Johnson becomes "Lady MacBird", and so forth. As Macbeth assassinates Duncan, so MacBird is responsible for the assassination of Ken O'Dunc; and as Macbeth is defeated by Macduff, so MacBird is defeated by Robert O'Dunc (i.e. Robert Kennedy). This action is significantly influenced by the Three Witches, representing Students, Blacks, and Leftists.
In a 2006 Washington Post interview Garson said she was not seriously accusing Johnson of complicity in the Kennedy assassination:
The play parodies sequences from Shakespearean tragedies including Macbeth, Hamlet, and Richard III, albeit with Texas and Boston accents. The action follows MacBird from the 1960 Democratic National Convention, when he becomes Ken O'Dunc's Vice-President ("Hail, Vice-President thou art!"), to Ken O'Dunc's assassination (at the urging of Lady MacBird), to Robert O'Dunc's victory over MacBird at the next convention.
Raise the flag of piracy, sing the song of victory
Glorious in battle are we
We've never known defeat, we never will retreat.
We live to hear the cannon roar,
And terror is our sempahore
Victoriously loathsome are we,
We rob the rich, the poor; then steal a little more.
Chorus:
Victory: we fight to win
Victory: is ours again
We are the scurge of the land and sea
Beastly pirates are we.
Masters of the briny sea,
We'll go down in history.
Couragous men who live by the sword
We deal in treachery, the kings of lechery.
Raise the anchor, trim the sail
We raid tonight if winds prevail
Invincible we fight to the end
United to a man, we need no battle plan.
Chorus
It's so pitable a sight, to see them walk the plank
They squirm and cry for mercy regardless of their rank.
Chorus
