This is the story according to what Eric told billboard.com.
"As they were leaving the Fenway show, [Springsteen] said, 'Wayne, what are you doing this weekend?' 'I'm going to see Eric Church.' 'No kidding,' and [Springsteen] took out a set list and wrote me a great note, filled up the whole back of the set list talking about how he was a fan of the song, how his family was a fan of the song," Eric said.
"He signed it and said, 'I hope we cross paths somewhere,' and told [LeBeaux], 'Make sure you deliver this to Eric.'"
Eric was blown away.
"It's a pretty incredible note," Eric continued. "It's the first time I've officially heard from him. I had heard he was a fan of the song, but it's the first time I officially heard. It means the world to me—and the set list is three hours and 37 minutes. That impressed me, too." (read more at CW.com)
