If you like the Mamas and Papas, this is the only CD set you need. Their timeless music evokes all the memories of when you first heard it. The combination of lyrics, melody, and harmony make this a group you can listen to forever. The hallmark of any group is the harmony which becomes one voice. Although my favorite group of all-time is the Mills Brothers, the Mamas and Papas come pretty close. Their original material is strong and their covers sound like their own whether it's Dancin' In The Street or Dedicated To The One I Love. As I said, this is all you need.
