JOE PAPP AND "MAC BIRD!" (1967)

The premise of the play "Mac Bird!' is that LBJ, at the time of production a sitting president, was responsible for the murder of JFK.

Pictured on the cover of the off-B'way program book, Rue McClanahan and Stacy Keach as Lady Bird and LBJ, the MacBirds.  The play ran at the Village Gate (downstairs) from February 22, 1967 until January 21, 1968.   I can find no record of the play ever being revived.

Theatre Atlanta also produced the play to great success in its 1967-68 season, with LBJ portrayed by Jay Garner, who would play the title role in "Red White and Maddox" the following season.
