After the success of “Please Please Me," George Martin was instructed by EMI to release the album as soon as possible, and he came up with the concept of filling the album with the atmosphere of a live performance.

In the session held on February 11, 1963, overdubs such as hand claps and harmonica were kept to a minimum, and the album was packed with a fast-paced live sound despite the simple band composition.

The 10-hour session consisted of 11 songs; the four continued recording without lunch, but John, who had been sick for several days, was not feeling well and licked his throat lozenges to get through the session.

Therefore, his voice lasted only one take on the final song “Twist And Shout," but it turned out to be a tremendous shout.
