Found this post on CourageCampaign.org... THANK YOU, PETER and PAUL!
Thank Peter, Paul & Mary for their support of marriage equality!
Read their cease-and-desist letter telling NOM to stop playing "This Land Is Your Land"
During their recent “Summer for Marriage” tour the National Organization for Marriage played a Peter, Paul & Mary recording of Woody Guthrie’s “This Land Is Your Land” during their rallies, without the permission of the artists.
Kathleen Perrin, a participant on the Courage Campaign's Prop8TrialTracker.com, contacted Peter Yarrow and told him. Yarrow called the use of the song by NOM “heartbreaking” and said that he would be contacting NOM asking them to stop.
