This week’s David Brophy's Frontline Choir sees stars much as Aslan, Paul Brady, and Sibéal Ní Chasaide join with them at Dublin Castle.
With their first live performance now under their belt, David announces to the choir that he wants to stage a final gig to celebrate and thank them and their fellow frontline healthcare workers.
In the run-up to the Dublin Castle gig, choir members grab any spare minutes they can between their busy shifts to rehearse at home, in work, or in their cars on their daily commute.

When the big day comes, they take to the stage to sing their hearts out.
John Doyle, the famous Temple Street Hospital porter who appeared on last year's Late Late Toy Show with Adam King, is also a member of the choir.
On singing with Aslan at Dublin Castle, he says: "If you had said to me eighteen months ago when Covid started that I would be in Dublin Castle with the most amazing group of people you would ever meet in your lifetime, I would have laughed at you.
"I've never sung with anyone before," he adds. "I've never even sang in the bathroom before."

Also on this week’s show is Health Service retiree Mary Walshe. She retired in March 2019 after 36 years' service. Following the death of her husband Greg in 2016 at the tragically young age of 49, Mary decided to take early retirement.
But she did not hesitate to return to the workforce when needed at the start of the pandemic, overseeing work at the Citywest facility.
Well-wishers attending the concert include Claudine and Robbie Keane, who have raised over 80,000 for the Mater Foundation during the pandemic.
The couple were inspired to raise funds following the care that Claudine's father received when suffering with Covid-19. He was seriously ill, but went on to make a full recovery.
David Brophy's Frontline Choir airs on Sunday at 6.30pm on RTÉ One.
