Pete Doherty's jail house rock

Pete Doherty is facing more time behind bars - for a prison concert.The troubled Babyshambles frontman is keen to go back to the jail where he was locked away and entertain the inmates.A source revealed to Britain's The Sun newspaper: "Pete knows the staff and some inmates from his stays and thinks it will be good for prison morale. He loves the idea of making it into a prison tour and recording the shows."Doherty is in talks with Gary Deighton, the governor of London's Pentonville prison, about a show, reminiscent of Johnny Cash's famous Folsom prison concert.The rocker, the on-off boyfriend of Kate Moss, spent two weeks in Pentonville earlier this year awaiting sentence on drugs charges.
