This is the way TIME wrote about overweight women in the sixties:
"The Mamas and the Papas are two beards, a beauty and a Big Bertha.
After knocking around the fringes of folk music separately for a few lean years, they joined forces in 1965 and made their first single, California Dreamin'. It went straight to the top of the bestseller charts, as did their next release, Monday, Monday. Papa John Phillips, 25, an Annapolis dropout, is the group's songsmith, and what his lyrics lack in depth his melodies make up in lilting appeal. Phillips' wife Michelle, a willowy ex-model, is the spiraling soprano; Denny Doherty, 24, sings a secure tenor.
Anchor girl is rotund (200 lbs.) Cass Elliot, 23, whose ringing contralto gives the quartet its oomph; Together they build a buoyant vocal blend that floats easily through intricate harmonic shifts, toying with rhythms that are as fresh and bracing as ocean breezes. The quartet is now on a highly successful college tour, stands to make $1,000,000 this year."
