I often wonder if George Martin was an even bigger piece of the jigsaw than is generally known ?
Lennon / McCartney seemed to be lost without him, post Beatles.
George Martin was the core musical driver and the conduit for the Beatles ever since their first recording audition with the group on the 6th June 1962 and the subsequent signing up of them by Parlophone. He channeled their creativity and was
the key influence behind them from that time, but especially and crucially from the recording of
Yesterday and onwards through
Sgt Pepper's Lonely Hearts Club Band and beyond, utilizing the advances in recording technology and mixing, with orchestration making an appearance. He kept the Beatles sounds in advance of being 'up to date', and controlled the artistic clashes and differences that occurred within the group. In short, he was crucial in the Beatles success, and is widely considered, especially by Sir Paul McCartney, to be the real '5th Beatle' rather than Stuart Sutcliffe.
