“Here on Earth, it feels like everything good is missing, since you left,” sings 14-year-old Jack in the video.

Jack, along with his younger sister Sarah, tragically lost post their parents at young ages.

The siblings’ mother Margaret ‘Mags’ passed away from an asthma attack in 2002. Later, father Jason remarried and moved the family to North Carolina, but in 2015, Jason was brutally murdered by his American wife Molly Martens and her father Thomas Martens.

Jason had allegedly grown concerned by Molly’s erratic behavior and was attempting to bring his children Jack and Sarah back to Ireland. Molly was demanding partial custody of the two children at the time.

In 2017, Molly and her father Thomas were both found guilty of second-degree murder of Jason Corbett. They are each serving 20-25 years in prison but are appealing the verdict.

Jack and his sister Sarah are now in the care of their father’s sister Tracey Lynch and are living back in Limerick in Ireland.

In a Facebook post accompanying Jack's video, Tracey wrote: “I am so proud of you Jack."

"We will never forget those we have lost, we don’t want to. Along with the greatest sadness of missing them lives a galaxy of gratitude for having shared love with them.”

On YouTube, Jack wrote, “This is dedicated to My Mam & Dad Mags & Jason Corbett and to anybody out there who has lost a parent.”
