The song ‘This land is your land’ was written and first sung by Woody Guthrie. 

Woodrow Wilson Guthrie, born in 1912 in Okemah, Okla, recorded the song during a marathon April 1944 session in New York for Moses Asch, who founded Folkways Records. 

"This Land Is Your Land" wasn't released by Folkways until 1951, however, the song was originally written in February 1940, when Woody Guthrie first arrived in New York City from Oklahoma. 

Guthrie had a keen ear for the recordings of Virginia's Carter Family and didn't shy away from borrowing. A 1930 gospel recording, "When the World's on Fire," sung by the Carters, must have provided the tune for what would become "This Land Is Your Land."

Over time, it's been sung by everyone from Bruce Springsteen to the Mormon Tabernacle Choir. However, activist and Guthrie's fellow traveller Pete Seeger has probably sung it more than anyone else.

While some claim "This Land Is Your Land" to be an alternative national anthem, others say it's a Marxist response to "God Bless America."
