The Beatles recorded together for a little over seven years. Between October 1962 and May 1970, they released thirteen albums and a number of tracks issued on standalone singles. The catalogue created in that short period has sold more than that of any other group in history and its commercial success continues - the world’s best selling album during the first decade of the 21st century was a collection of The Beatles’ chart-topping singles called 1. But the group’s significance stems not just from huge sales figures. Their music has inspired generation upon generation of musicians, songwriters and producers.
