David Leaf is back to talk about his new book God Only Knows: The Story of Brian Wilson, The Beach Boys & the California Myth. The release includes the entirety of David's seminal 1978 book, plus its 1985 update, and most excitedly, a substantial new update that brings the story to the present. He tells us about his long-ago mission to befriend Brian and help him finish Smile; navigating Eugene Landy, Brian exorcising his demons and where he is at today, and The Beach Boys' 60th anniversary.
