The 99-year-old former veteran, who was aiming to raise just £1,000 for the NHS by walking up and down his garden 100 times before his 100th birthday this week, has hit the number one song.
His charity collaboration with Michael Ball and The NHS Voices of Care Choir on the song You'll Never Walk Alone has topped The Official Big Top 40 chart on Sunday.
It comes after he raised millions by walking up and down his garden in his home in Marston Moretaine, Bedfordshire.
The single is also raising money for the NHS, as well as the millions he raised by walking.
Captain Moore's song also joins Dame Vera Lynn and Katherine Jenkins' duet of We'll Meet Again, which entered the chart at number three.
His daughter Hannah Ingram-Moore couldn't believe it when she found out and took to her social media to share her pride for her dad.
She told Will Manning on the chart show: "Can anything else happen to us, do you think?!
"We are working our little socks off as you can imagine, we are fully Team Tom!
"Thank you for supporting us all and thank you to the British public, we really appreciate it."
His grandson Benji, 16, weighed in: "He's as true a Yorkshireman as you're going to get, he takes everything in his stride.
"He won't brag about it at all, he's probably one of the most humble men you’ll ever meet in your life.
"But I think quietly he's really loving it."
