Context: "Let It Be" is a song by the English rock band the Beatles, released in March 1970 as a single, and (in an alternate mix) as the title track of their album Let It Be. At the time, it had the highest debut on the Billboard Hot 100, beginning its chart run at number 6. It was written and sung by Paul McCartney. It was their final single before McCartney announced his departure from the band. Both the Let It Be album and the US single "The Long and Winding Road" were released after McCartney's announced departure from and the subsequent break-up of the group. The alternate mix on their album Let It Be features an additional guitar solo and some minor differences in the orchestral sections.\n\nQuestion: who wrote the lyrics to let it be?
