Beatles producer George Martin dies at age 90; he is described as 'fifth Beatle'
One of many men described as the 'Fifth Beatle' over the years
When news broke on Tuesday that the “fifth Beatle” had died, you might be forgiven for asking “which one?”
In this case, the honorary member in question was the band’s former producer, Sir George Martin, who passed away at his English home at age 90.
“If anyone earned the title of the fifth Beatle, it was George,” said Paul McCartney on his Facebook page, of the producer who spent seven years crafting one of the most successful bands in history.

Martin might have “earned” the coveted fifth Beatle crown – but that hasn’t stopped it being attributed to many more people over the years.
From former manager Brian Epstein, to original drummer Pete Best, we take a look at other worthy (some less so) contenders for the title. As for who really deserves the “fifth Beatle” moniker… we’ll leave that one up to you.
George Martin, producer

Not only did the legendary music producer give the band their first recording contract, he also played piano on many of their songs, including “In My Life,” and “Lovely Rita.”
“From the day that he gave The Beatles our first recording contract, to the last time I saw him, he was the most generous, intelligent and musical person I’ve ever had the pleasure to know,” added McCartney on Tuesday.

“He was like a second father to me.”
Brian Epstein, manager

Epstein is often credited with “discovering” the Beatles in 1961, during a performance at the Cavern Club in Liverpool.
The young manager had a huge impact on the band’s early years, working hard to set up that fateful meeting with producer Martin, then head of EMI’s Parlophone Label.
However, his time with the band was cut short in 1967, when he died from an apparent accidental drug overdose at age 32.
Neil Aspinall, schoolmate and road manager

Before he was their roadie, Aspinall was Paul McCartney and George Harrison’s schoolmate in Liverpool.

From driving the band to gigs and lugging their kit onstage, Aspinall moved up the Beatles management ranks, later becoming the group’s personal assistant, and ultimately the CEO of Apple Corps until 2007. He died in 2008 from cancer at age 66.
Stuart Sutcliffe, original bassist
Look closely at the “Sgt. Pepper’s Lonely Hearts Club Band” album cover, and you’ll see the unremarkable black-and-white image of a young man in the far left corner, third from the top. That’s Stuart Sutcliffe, the band’s original bassist.
Sutcliffe was there back when the Beatles were a five-piece band, performing night after night during their formative days in Hamburg, Germany.
But he left the band at the end of their trip in 1961 to resume his studies (Sutcliffe was a talented painter who struck up a friendship with John Lennon at art school) and be with his sweetheart, Astrid Kirchherr.
He died the following year due to a brain hemorrhage. He was 21.
Pete Best, original drummer

Does Pete Best still rue the day he was ditched from arguably the world’s biggest band? We can only guess.
But the drummer still had two years with the Beatles before he was apparently dismissed by Epstein in 1962, and replaced with Ringo Starr.
