This book does provide a great concise history of the Mamas and the Papas and does have all 16 songs it claims, but if you are looking for the harmonies in the songs DO NOT BUY THIS BOOK. It only contains the melody and not a full instrumental section. This was a sore dissapointment for me because I already know all the melodies and their history. Beware: if you are looking for a REAL music book... this is not the one for you. If you are just starting out reading music or playing the piano, its a very concise book with 16 of their greatest songs.
