George Martin - often referred to as the Fifth Beatle due to his work with the infamous band - has died at the age of 90.
The tragic news was first shared on Twitter by Ringo Starr, who shot to fame with The Beatles as their drummer and vocalist.
Sharing a photograph of himself with the legendary producer, Ringo wrote: "God bless George Martin peace and love to Judy and his family.
“Thank you for all your love and kindness George peace and love xx."
Other stars to share their condolences included John Lennon's son Sean, who shared a picture of Martin on his Instagram, writing: "R.I.P. George Martin. I'm so gutted I don't have many words.
“Thinking of Judy and Giles and family. Love Always, Sean."
Mark Ronson also took to Twitter to share his condolences, writing: “Thank you Sir George Martin: the greatest British record producer of all time.
“We will never stop living in the world you helped create.”
Former Oasis rocker Liam Gallagher added on his Twitter page: "Sir George Martin RIP LG x"
And singer Josh Groban also paid tribute, writing: "Every time I record at abbey road I geek out and play with the mics sir George Martin used.
“What an ear, what a life, what a legacy."
Gary Kemp, Regina Spektor, Fearne Cotton and more also flocked to Twitter to pay their respects - reminding us once and for all that George Martin touched and influenced the lives of many in the music industry.
Singer and music producer Midge Ure also paid homage on Good Morning Britain to ‘The Fifth Beatle’ Sir George Martin following his death, calling him ‘one of the most wonderful people’ he’d ever met.
Speaking to Piers Morgan and Susanna Reid, Midge said: “Personally he was one of the most wonderful people I’d ever met. I described him many times in the past as a cross between your favourite school teacher and a father, he was such a loving wonderful guy, and incredible, incredibly musically knowledgeable.”
On the legacy Sir George left behind, he added: “I mean George obviously was known for his work, his legendary work with The Beatles and Gerry and the Pacemakers and that whole sixties melody thing, but he was also responsible for giving us stereo, giving us music that we could listen to in stereo, because up until George got involved with the music industry, everything was a mono and we used to listen to these monophonic recordings and George insisted that they bring in a three track tape recorder from America, so he was technically involved in all of that.”
The Beatles had been turned down by several record labels when George met with them at Abbey Road in June 1962. He went on to sign the band to his Parlophone label - and music history was made.
In his 1979 book All You Need Is Ears, Martin explained his relationship with The Beatles, writing: "I must emphasise that it was a team effort. Without my instruments and scoring, very many of the records would not have sounded as they do.
“Whether they would have been any better, I cannot say. They might have been. That is not modesty on my part; it is an attempt to give a factual picture of the relationship.”
He was responsible for producing almost all of the bands songs, adding his own unique touch to the arrangements of Strawberry Fields, Yesterday, and A Day In The Life.
It’s therefore unsurprising that he was made a Knight Bachelor in 1996 for his services to the music industry.
George is survived by wife Judy Lockhart Smith and their children Lucy and Giles, as well as children Alexis and Gregory from his marriage to Sheena Chisholm.
Our thoughts are with them at this tragic time.
