The Mamas and the Papas’ legacy is being celebrated with a 2-LP, 31-track set that brings together on vinyl the A and B side of every single the group released, all in their rare mono single mixes. The Mamas and The Papas: The Complete Singles arrives on Dec. 6 via Real Gone Music.

Over a two-year period, from 1965-1967, the singing quartet with the beautiful harmonies earned six Top 5 singles including their first hit, “California Dreamin’” (#4), soon followed by “Monday, Monday” (#1), “I Saw Her Again” (#5), “Words of Love” (#5), “Dedicated to the One I Love” (#2) and “Creeque Alley” (#5).

The collection has been remastered by Aaron Kannowski, and includes notes by co-producer Ed Osborne that feature quotes drawn from extended interviews with Michelle Phillips and Dunhill label head and producer Lou Adler. The gatefold package also includes a number of rarely seen images of the group.

A 2016 2-CD version, also from Real Gone Music, features a whopping 53 songs, with many of their solo releases, including 16 from Mama Cass Elliot, like “It’s Getting Better” and “Make Your Own Kind of Music.”

With the debut of their first hit, “California Dreamin’,” on the charts in 1965, the Mamas and the Papas – Cass Elliot, Michelle Phillips, John Phillips and Denny Doherty – proclaimed themselves to be a potent new force in the burgeoning West Coast folk-rock movement, announcing to the world that something special and beautiful was happening in California.
