The Beatles began working their way through their live set song by song, the number of takes varying on each, and finished at 10:45 pm – less than 13 hours later – capturing, in essence, an authentic representation of the band's Cavern Club-era sound. The day ended with a cover of "Twist and Shout", which had to be recorded last because John Lennon had a particularly bad cold and Martin feared the throat-shredding vocal would ruin Lennon's voice for the day.
