Dads go free with a paying child to the family festival in Bletchley.
Britain's Got Talent semi-finalist Bailey McConnell will join city singers Toffees,The Hallows and Emily Haig at H-Fest for a full day of entertainment at The Scots Club, Bletchley.
Mark and Dawn Allen are throwing the event to raise money in memory of their four-year-old son Henry who died following a brave battle with Neuroblastoma.
Dawn said: "Henry's legacy is all about helping others battling childhood cancer just like he did. Nothing would make us happier than putting a beautiful smile on their face by being able to give them treats and fulfil their wishes.
"The Henry Allen Trust's financial grants help ease the burden many families face when their child is sick. Please help us support them by coming to H-Fest - a truly one-of-a-kind event which will help Henry continue his last wish.
"Hope, dream, believe and help us achieve."
Entry is £2 per adult - but as a special Father's Day treat all dads go free when with a paying child.
Entry for children is £1, under-threes go free.
The Henry Allen Trust's H-Fest runs from 12-8pm on Sunday and includes stalls, circus skills, face painting, well-bring treatments, refreshments and fantastic entertainment.
Bailey McConnell, who is a patron of The Henry Allen Trust alongside Emily Haig, said: "I'm so proud to be a patron and be able to perform at an event like this.
"Everyone who comes on Sunday will help bring happiness to children battling this awful disease."
