Convicted paedophile Rolf Harris is believed to have written a song mocking his victims as money-grabbing "wenches".
In a letter obtained by the Mail on Sunday, the disgraced entertainer said his victims were "joining the feeding frenzy" by getting their "hooks into his dough".
Harris also said his life behind bars was "no hardship really".
He received a six-year jail term last year for a string of sex attacks on girls as young as seven.
His letter was reportedly sent from Stafford prison to a friend, who handed it to the newspaper.
One line of the song, which the 85-year-old says he would like to set to country rock music, reads: "Perhaps you believe you're pretty still, some perfumed sultry wench?"
Other lines say: "Make him burn, get your 50-year-old hooks into his dough" and "Make him burn, burn, burn. Come and join the feeding frenzy, girls."
Last month the Crown Prosecution Service was handed a "full file" of evidence about further allegations against Harris, according to sources.
He was unmasked as a predatory paedophile last July when he was found guilty at London's Southwark Crown Court of 12 indecent assaults,
Sentencing judge Mr Justice Sweeney said Harris showed no remorse for his crimes.
He said: "Your reputation lies in ruins, you have been stripped of your honours, but you have no one to blame but yourself."
