About David Cassidy
David Bruce Cassidy was an American actor and musician. While he was best known in the United States for his role as Keith Partridge in the 1970s musical-sitcom The Partridge Family, he was an international success in his solo career as a singer. For a period, he was the highest paid entertainer in the world. Cassidy's father, Jack, is credited with setting his son up with his first manager. After Cassidy made small wages from Screen Gems for his work on The Partridge Family during season one, when it became a great success, Aarons discovered that he had been underage when he signed his contract. In Britain, Cassidy the solo star remains best known for "Daydreamer", "How Can I Be Sure", and "Could It Be Forever" (UK number 2/US number 37), all released during his 1971–75 solo chart peak. Aarons became an authority figure and close friend to Cassidy and he credits her as the driving force behind his on-screen success.
