For instance, Pam Morrison comes across as angelic and squeaky clean, when in reality she was a manipulative heroin addict.
But Pam's parents owned a 50% interest in Morrison's recordings (the other half owned by Morrison's parents). And Pam's parents would not give permission for Stone to use the recordings unless Pam was portrayed in a good light.
Well, a 50% interest in Morrison’s interest. The band members also owned a piece.
