“My dad wrote a book before he died (during heart surgery when Anderson was 10) about his family growing up in Mississippi. And because he died when I was so young, a lot that I know of him came from that book. I wanted to write a letter to Wyatt about this crazy and unusual part of his family’s past,” he says.
