Diana concert loses top acts to Live Earth

Organisers of the memorial concert for Princess Diana are struggling to secure high profile artists for the event after losing superstars Madonna and Red Hot Chilli Peppers to this year's Live Earth charity concert.

The sons of the late princess, Prince William and Prince Harry, are reportedly pressuring concert bosses to re-think the current line-up, which includes 1980s stars Jason Donovan and Donny Osmond, and book trendier and more current acts.
