It was only the band’s second number one, issued as Beatlemania was in its infancy, but newly compiled figures show 'She Loves You' to be the biggest-selling Fab Four track released in the UK.

The 1963 single topped a chart of the act’s greatest sales tallies pushing its follow-up, 'I Want To Hold Your Hand,' into the second spot.

The Official Chart Company — which puts together the weekly Top 40 — has trawled its records to pull together an all-time bestseller list of the band’s singles, including the many re-releases over the years.

Despite the later acclaim for the band’s innovations and experimentation during the studio-bound years, the list is dominated by tracks up to and including 1965.

The outstanding English composers of 1963 must seem to have been John Lennon and Paul McCartney

As well as 'She Loves You' and 'I Want To Hold Your Hand,' the Top 5 is made up of 'Can’t Buy Me Love,' 'I Feel Fine' and the double A-side 'Day Tripper/We Can Work It Out.'

The figures show that 'Love Me Do,' the band’s first chart hit that reached No 17 on its initial release, went on to outsell the No 2 hit that followed it, 'Please Please Me,' as well as later number ones such as 'The Ballad of John and Yoko,' the figures reveal today.
