Actually I swear that Cass was much heavier than even that in some points of her (too short) career. I know she wasn't tall but I have seen pics of her where she seems 50lbs heavier than that.
One of my favorite female vocalists, by the way, of the 20th Century.
I like some of the Mamas and the Papas. Good harmony, but lotsa bad hippie music too.
Cass Elliot's version of "Dream a Little Dream of Me" set the standard. Just a beautiful performance.
