Criminal lawyers by day and folk musicians by night, it's a wonder Tom Percy QC and Jonathan Davies find the time to hit the Perth charity event circuit.
The pair, both prominent Perth barristers, will front their Irish/country band, the Gang of Three, in an one-off acoustic performance for dozens of sick children and their families at Ronald McDonald House, which provides accommodation for regional families with seriously ill children, on Friday night.
WA rocker Chris Murphy, who got his break on Australian Idol in 2006, will kick off the 'house party' with a solo performance and Australian cricketer Adam Gilchrist, Emirates Western Force players and world championship netballer Caitlin Bassett will mingle with residents of the house.
Percy said the Gang of Three was always happy to lend a hand to charities doing good work in the community.
"We always make time," Percy told AAA.
Esperance boy Jaydon Hurst, 11, who has lived at RMH with his mum for the past four months while receiving treatment for nasopharyngeal carcinoma, said he had been looking forward to the party for weeks.
"It has been boring because my sisters have left," Jaydon said.
"I'm excited to see Gilly again."
Ronald McDonald House executive officer Alison Salmond said the annual party to launch McHappy Day was an uplifting experience for the children, who spent almost every day in hospital.
"Unfortunately our house is at fully capacity every night, which means our resources are stretched," Salmond said.
More than $18.5 million has been reaised since McHappy Day began in 1991. This year organisers aim to raise $3 million when celebrities take to McDonalds restaurants across Australia on Saturday.
