Pop acts Alexandra Burke, Pixie Lott and McFly have taken part in a special U.K. Tv show highlighting the need for organ donations across Britain.

The stars all took part in the From The Heart drive, which aired on Wednesday night (13Feb13), to raise awareness of the National Health Service's (Nhs) Organ Donor Register.

Lott performed a rendition of Peter Sellers and Sophia Loren's spoof doctor/patient song Goodness Gracious Me with comic Rowan Atkinson, while MCFly stars Danny Jones, Tom Fletcher, Harry Judd and Dougie Poynter competed in a 656-foot (200-metre) race with heart transplant athlete Joe Matthews.

Burke, who performed during the programme, spoke of how the issue affects her - her mother, former Soul II Soul star Melissa Bell, is battling kidney failure and desperately needs a transplant.

She told host Dermot O'Leary, "For me and my (siblings) it's very difficult because that's our mum and the day I found her on the bed and pretty much unconscious (due to her illness) when I called the ambulance is a day that will never leave my side."
