The video clip I linked to yesterday of Pete Seeger singing "This Land is Your Land" on the Capitol Mall has since been removed from YouTube by HBO, who claims copyright for the broadcast.
In that clip, Pete sang the following verse:
There was a big high wall there that tried to stop me;Apparently, the irony of this is completely lost on HBO...
Sign was painted, it said private property;
But on the back side it didn't say nothing;
That side was made for you and me.
