True story: Cass was a real smart lady, with an I.Q. of 165. Also, she had a hell of a time getting into The Mamas and Papas. In his biography "Papa John", John Phillips says he was reluctant to let Cass into the group, not only because of her size, it was also because her alto voice couldn't hit the high notes John wanted for the group sound. She would follow the band everywhere, getting jobs wherever they played, just to be around. Then, one strange day, Cass was walking past a construction site when a lead pipe fell and hit her on the head, knocking her out. After three days in the hospital with a moderate concussion, she joined a rehearsal the band was having- and she could hit the high notes John wanted! Cass was then, finally, invited to join The Mamas and Papas.
