Shea gives a definitive account of the group's short time together, from their hitmaking approach with legendary producer Lou Adler to John's unique songwriting to tours and friendships with other musicians riding the folk-rock wave. He explores the emotional vicissitudes that came with being in the Mamas & the Papas, from Cass's unrequited love for Denny, his affair with Michelle, and the ebb and flow of dysfunction in John and Michelle's marriage. And he explains how it all came to a crashing end with John's brainchild, the Monterey Pop Festival, which should have launched the group even further into the musical stratosphere, but only served to be their undoing. Drawing on new interviews with former bandmates, session musicians, family members, and many others, All the Leaves Are Brown is a layered, revelatory tale of overnight stardom and its many pitfalls.
