“This Land is Your Land”
Verses four and five, as performed at the pre-inaugural concert:

A great high wall there tried to stop me
A great big sign there said “Private Property”
But on the other side …. it didn’t say nothin!
That side was made for you and me!

Nobody living can ever stop me,
As I go walking that freedom highway;
Nobody living can make me turn back
This land was made for you and me!

Update: HBO has put up a sign on the video saying “Private Property”. Search YouTube for Seeger and Obama; I found half a dozen or more. This song is made for you and me.
