Seven year old Harry Addy has got a lot o' livin' to do.
It's now or never as his parents look to raise £70,000 for life saving treatment in Germany, and their cousin Stacey Harper is boosting their funds with a world record attempt.
She will try to be his good luck charm and run this year's London Marathon dressed as Elvis.
Harry, from Rivermead, Stalham, has a spinal cord tumour and rare brain disease, and needs proton therapy overseas after being turned down by the NHS.
Ms Harper, 40, of Old Catton, will run her eleventh marathon, and fourth London marathon, this year dressed as the Graceland singer to help pay for the trip.
After searching world records she discovered one has not yet been set for the fastest woman to run a marathon dressed as Elvis.
'My mum is a massive Elvis fan, so I grew up in a house called Graceland and listening to all his music,' she said.
'I wanted to try to get a world record so I saw the Elvis one and thought it would be a brilliant one to do.
'The costume was bit big so mum helped to make it fit properly. I have been out and about in the suit and I'm sure people will have seen me running around Old Catton and Norwich in it.'
Ms Harper is hoping for a cool day. If she removes the wig or glasses at any stage of the race she will lose the record. Blue suede shoes are optional.
She is hoping to raise around £2,000 for Harry's treatment, and added what he has been through is 'heartbreaking'.
'Every time he is ill or has a temperature above 38 he gets rushed to hospital and he has to spend three days there,' she said.
'He is just a normal little boy and you would not know anything was wrong to look at him.
'It is heartbreaking to see a child go through what Harry has.'
Harry had an operation to remove the tumour a few years ago and now has leptomeningeal disease in the centre of his brain.
His dad, Jamie, said: 'He's had to learn to walk again, made countless hospital trips, had MRI scans, physiotherapy and an 18-month course of chemotherapy to stop the tumour from growing. But it's still growing and he now has a disease in his brain.
'The poor little boy is just seven and it seems the whole world has dropped on him.'
