In the UK, the Beatles had ELEVEN consecutive No.1 hits from 'From Me To You' in 1963 to the double A sided 'Yellow Submarine' / 'Eleanor Rigby' in 1966. They then had a further SIX consecutive chart-toppers from 'All You Need Is Love' in 1967 to 'The Ballad of John & Yoko' in 1969.
Had it not been for the double A side 'Strawberry Fields Forever' / 'Penny Lane' inexplicably stalling at No.2 between those two runs, the Fab Four would have chalked up a mind-blowing EIGHTEEN consecutive No.1s!!
The Beatles spent an incredible 69 weeks at No.1 in the 60s and 333 weeks in total on the UK charts.
As a footnote, the disc that kept 'Strawberry Fields / 'Penny Lane' off the top of the charts was Engelbert Humperdinck's 'Release Me'.
