I grew up listening to The Mamas and the Papas and really was entranced by their music. In the 60" and & 70's there were no mobile phones and internet to get information on or keep up to date with singers and bands so there was very little available about their lives.
The book Dream a little dream of me covers not only Cass Eliot but you get to know the other members and the inter relationships and all manner of things previously unknown.
I would recommend this book to anyone wanting insight into a period of music that is the best of all time!
