Mama's Big Ones is a compilation album of mostly previously-released material (as detailed below) by Cass Elliot.

[1][2][3] Elliot would in 1971 claim that at Dunhill she had been "forced to be so bubble gum that I'd stick to the floor when I walked",[4] and in fact Elliot's solo singles had been progressively less successful, Dunhill president Jay Lasker commenting after Elliot's sixth solo single stalled at #42 in early 1970 "'New World Coming' has gotten great airplay because it came along and expressed hope in the midst of despair.

[1] Mama's Big Ones featured nine of Elliot's ten Dunhill single releases - omitting 1968's "California Earthquake" - and adding the Mamas & Papas' hit "Words of Love" which featured Elliot as lead vocalist.

The album can be seen hanging on the wall of the character Leah in the 1996 British film Beautiful Thing while she is listening to "One Way Ticket".

Songs from the album (namely "It’s Getting Better", "Make Your Own Kind of Music", and "New World Coming") were used on the American television series Lost.
