Rick Springfield (born Richard Lewis Springthorpe; 23 August 1949) is an Australian singer-songwriter, musician, and actor. He was a member of pop rock group Zoot from 1969 to 1971 and then started his solo career with his début single "Speak to the Sky" reaching the top 10 in Australia. In mid-1972, he relocated to the United States. He had a No. 1 hit with "Jessie's Girl" in 1981 in both Australia and the US.
"Mama" Cass Elliot, Baroness von Wiedenman (19 September 1941 – 29 July 1974), born Ellen Naomi Cohen, was a noted American singer who performed with The Mamas & the Papas. She then went onto a successful solo career, releasing nine albums. Born in Baltimore, Maryland, she spent most of her childhood both in Baltimore and Alexandria, Virginia, a suburb of Washington, D.C. Elliot was widely considered the most charismatic member of the Mamas & the Papas due to her sense of humor and optimism, in part because of her large size and weight.
