2012 marks the 100th birthday of Woody Guthrie, the man who wrote “This Land is Your Land” and countless other folk classics, a man who has had an undeniable impact on the world, as composer, singer, activist and legend.

The rousing “Woody Sez: The Life & Music of Woody Guthrie” at Theater J illustrates that impact. Devised by David M. Lutken with Nick Corley, “Woody Sez” tells the story of Guthrie’s life from the time he started singing for money at six years old.
