Dave Grohl dreaded writing his book's chapter about Kurt Cobain

Dave Grohl's new book, The Storyteller: Tales of Life and Music, is full of funny anecdotes and revelatory tales from the two-time Rock and Roll Hall of Famer's fascinating life.

While Grohl's tone is typically sincere and optimistic, the book has its share of down moments, none of which is more gutting that the former Nirvana drummer's recollection of Kurt Cobain's 1994 suicide.

For years Grohl refused to say much publicly or privately about Cobain or the end of Nirvana. And writing about Cobain proved to be the biggest challenge of crafting the memoir.

"'Cause I was scared to write it," Grohl said of the book's final chapter in a conversation with Amanpour & Co. "It's one thing to write about getting stitches when you're 12 years old or it's one thing to write about taking your kids to the daddy-daughter dance. It's another thing to write about something that you've barely spoken about with people close to you. I mean, I revealed some things in that story that I've never told my closest friends. I was scared to write it.

Grohl so dreaded the Cobain chapter because he knew he had to write it; Cobain's life and untimely death are essential to Grohl's own story. And reader's surely expected some insight.

"First of all, I knew what people wanted me to write," he continued. "I think that people have a lot of unanswered questions — as do I. So I decided to write in a much broader emotional sense — the process of loss or grief and mourning, and how that's determined and how it differs from person to person. Yeah, it was a tough one to write."
