Captain Tom Moore has become the oldest artist to reach number one on the UK singles chart, as his rendition of 'You'll Never Walk Alone' reached top spot in time for his 100th birthday at the end of the month.
The Second World War veteran recorded a duet with singer Michael Ball – a cover of Rodgers and Hammerstein's original song.
Upon discovering the news, Captain Tom said it was "out of this world".
It beat 'Blinding Lights' by Canadian singer The Weeknd, who, on Thursday, took to Twitter to encourage his fans to back Tom and give the veteran a number one single, in time for his 100th birthday on 30 April.
"Everyone in the UK please support @captaintommoore / @mrmichaelball single so this incredible 99 yr old war veteran, walking for the British National Health Service @NHSuk & now raised $35 Million can have a No 1 for his 100th birthday in the UK," The Weeknd posted.
"We're routing for you."
Captain Tom then posted from his Twitter account, thanking him for the "kind gesture".
The Weeknd then tweeted again, to wish the Army veteran a happy birthday.
The cover released by Captain Tom and Michael Ball features a spoken introduction from the Army veteran, who says: "Hold your head up high...and don't be afraid of the dark."
The duet has become an anthem for medical staff during the coronavirus pandemic and also features the NHS Voices of Care Choir.
The song is one of the ways the war veteran has been raising money for NHS Charities Together, to thank the "magnificent" staff who recently treated him for a broken hip and cancer.
The veteran has also been given a Pride of Britain award.
Mr Ball said: "There isn't one of us who has failed to be inspired by Captain Tom Moore.
"It is one of the single greatest honours of my career to sing with this genuine national hero, supported by the incredible NHS Voices for Care Choir.
“Not only is he the biggest single fundraiser in British history and a decorated war veteran, he is the most charming man you could ever wish to meet. Hopefully he can now add singing star to his many talents.
"Wouldn't it be wonderful if we could give him a number one record for his 100th birthday!"
Capt Tom said: "I never in my wildest dreams imagined I would be releasing a single with Michael Ball OBE, but I also never thought it possible for me to walk in the garden and raise millions.
"So why not sing, spread some cheer and again – raise money for our national heroes. NHS this one is for you!"
Speaking from his home in Bedfordshire, Captain Tom said: "What wonderful news to receive today, a number one single and record-breaker too – my grandchildren can't believe I am a chart-topper!
"I have to thank Michael Ball, the NHS Voices Of Care Choir and everyone behind the scenes, who shared their talents and expertise in order to raise money for the NHS, to whom we owe so much.
"And, of course, the public for buying the single and donating – we're in this together, and I am forever grateful for your support.
"And this just proves you'll never walk alone."
Captain Tom will become the first centenarian to top the charts as he will turn 100 on Thursday, while he still holds the number one spot.
