A father whose daughter was born with a rare heart condition will sing for 24 hours this weekend to help the hospital which saved her life.

Julian Hill will attempt to get the world record for endurance singing on a video game when he takes to the stage at the Ambassador's Bloomsbury Hotel in London.

The 29-year-old from Tolwin Walk, off Sprowston Road, will finish the challenge at 10am on Saturday morning – exactly a year after his daughter was taken into the operating theatre for life-saving surgery.

Amelia, who will be two at the end of April, was born with a heart problem called Tetralogy of Fallot, which meant she stopped growing after six months.

As reported in the Evening News on February 6, surgeons at Great Ormond Street Hospital in London had to open her rib cage and stop her heart beating to fix it in a five-hour operation.

Now the freelance TV editor is hoping to raise �1,500 for the hospital through his challenge.

Mr Hill said: 'It is a bit intimidating but I'm feeling confident about doing it.

'The hard part is staying focused.'

He will drink cold tea with rice milk to keep his voice going and sing lots of rap music as this is less demanding on his voice than other karaoke songs.

Starting this Friday at 10am he will sing around 450 songs, using Playstation game SingStar.

He is allowed to take five-minute breaks every hour. Mr Hill, who has raised �1,000 so far, said: 'Any parent who leaves Great Ormond Street has an incredible sense of gratitude and this was my silly idea of what we can do to pay them back.

'We saw first-hand how donations really do make such a difference to the patients and their families.

'The hospital is an amazing place which has touched the lives of so many children and their families and I want to show my thanks for saving my daughter's life, not only by raising money, but also raising awareness about the hospital.'
