Dame Vera Lynn has urged fans to "keep smiling and keep singing" in the coming months as coronavirus continues to spread.
The Forces Sweetheart shared her uplifting message on her official Twitter page as she celebrated her 103rd birthday.
As a nod to the "difficult times" the nation is currently facing due to coronavirus, she posted a short burst of the new video for her signature wartime tune, We'll Meet Again.
Originally recorded in 1939, the song is credited with boosting British morale through World War II.
The video features original archive footage of Dame Vera and a special voiceover from the singer, which she recorded at home.
As the nation embraces social distancing measures, and with many in self-isolation in a bid to avoid COVID-19, the song's theme of "meeting again" can be seen to take on a new relevance.
Dame Vera has said she hopes the nation will also take hope from the song's positive message: "Keep smiling through; Just like you always do; 'Til the blue skies drive the dark clouds far away."
The message seems particularly relevant for the older generation, especially those who are 70-plus and considered to be at greater risk.
A raft of events celebrating the 75th anniversary of VE Day have been cancelled or postponed amid the outbreak as the government advises the public to avoid mass gatherings and self-isolate.
Comparing the current crisis with the hardships of wartime, Dame Vera said: "All around the world, people are facing extremely difficult times. It is likely that we will all have to make hard decisions in the coming months."
She went on: "I am reminded of World War II, when our country faced the darkest of times and yet, despite our struggles, pulled together for the common good and we faced the common threat together as a country, and as a community of countries that joined as one right across the world."
Her message to fans was simple: "Music is so good for the soul... keep smiling and keep singing".
In 2010 Dame Vera made history as the oldest living artist to have a number one album.
She is also the only recording artist in the world to have spanned the pop charts from the 1940s to the 21st century.
