Legendary music producer, often nicknamed as 'the 5th member of the Beatles', Sir George Martin has died today at the age of 90. 

Beatles drummer, Ringo Starr, took to Twitter to confirm the news this morning writing: "God bless George Martin peace and love to Judy and his family love Ringo and Barbara George will be missed xxx."

The infamous producer boldly signed the Beatles after hearing a rough demo in 1962, despite label Parlophone Records being focused mainly on comedy and jazz at the time. 

George went on to hone the sound of the group and produced nearly all their songs. 

The father-of-four became an influential name in the music business with his career spanning over sixty years, 30 number one songs to his name in the UK and 23 in the US. 

Stars have taken to Twitter today to honour the producer:
