Boyzlife are hoping their latest single will become an "anthem" for the elderly during the coronavirus pandemic, according to Keith Duffy.
The pop supergroup, formed of Duffy and Westlife's Brian McFadden, are donating the profits from their single You Needed Me to the charity Age UK.
The song, originally recorded by Boyzone in 1999, features the Royal Philharmonic Orchestra and appears on their forthcoming debut album, Strings Attached.
Duffy, 45, said he wanted to let the elderly and vulnerable know they could find help amid the lockdown.
He told the PA news agency: "We want to let people know that the elderly are there, and that people care, and that Age UK can fight your corner for you if you are elderly, and help you out if you are unwell.
"If this song becomes an anthem for Age UK, and people listen to it, the awareness is created.
"The lyrics lend themselves very well to reaching out and helping other people - picking somebody up when they are down, letting people know there is somebody out there who cares.
"That's the message we are putting out there, that's what this song does."
Duffy said recording the album had been a "very long but very worthwhile" process, one they only finished weeks before the lockdown.
McFadden, 39, who is working as an NHS volunteer responder during the outbreak, said many Westlife fans were among the elderly left isolated.
"Right now the people who are being affected the most are the elderly," he told PA.
"Age UK is a fantastic charity that helps them, getting food and medicine to people, just even simple things like talking to people on the phone that are lonely.
"Boyzone goes back 26 years, so lot of our fans who were maybe in their 40s when we started, they are now seen as elderly.
"We wanted to do something for them."
