I recall "Utah" Phillips telling a simular story about when he lived outside Spokane and the FBI was bugging his phone because of his political activities in the sixties.Armed with that valuable piece of information, he told his wife on the phone, whatever you do, DON'T dig up the potato field till I get home. And when he arrived home from his concert touring, he was most satisfied as to how well the feds can dig something up when they put their minds to it. Now he could plant his crops in a freshly turnd field.
I don't recall if that was ever recorded.
