David Cassidy Goes After 'Partridge Family' Fortune

LAS VEGAS -- A CNNMoney and CNN Special Investigations Unit exclusive report. "Hollywood Hustle?" will be part of a CNN Presents hour on Sunday, Aug. 7 at 8 p.m. and 11 p.m. ET.

In a hotel suite just hours before going on stage, David Cassidy is signing the famous lunchbox from "The Partridge Family," the 1970s television show in which he starred and performed his hit records.

Today, 37 years after the show went off the air, Cassidy is still filling showrooms with hits like "I Think I Love You."

But he won't be singing that song to Sony, which owns "The Partridge Family."

Cassidy told CNN that Sony Corp. (SNE) has failed to pay him "a fortune" for what he's owed for merchandise from the show.

"It's just ludicrous and unfair and wrong. It's greed," the 61-year-old actor said.
