As a direct result of The Beatles’ success, Dr Timmis claimed, the scanner’s inventor, Sir Godfrey Hounsfield, was able to devote about four years developing the scanner from its 1968 prototype, to something that could be used in a clinical setting. His work was done in the Central Research Laboratory, a facility near Heathrow airport that was part of the EMI Group. Having sold 200 million of the Fab Four’s singles, (at seven inches, almost enough vinyl to stretch the length of the equator) the Beatles’ record company, EMI, was able to fund Hounsfield to do his research and the scanner was ready be used in hospitals in the 1970’s.
On average there are 8.24 chords per song for the forty-six early originals the Beatles performed on record from 1962 till the end of 1964.
