6. The Beatles - 'Twist and Shout'
The Beatles cut their 1963 LP Please Please Me in a single day, so when it came time for John Lennon to sing a cover of the Isley Brothers' "Twist And Shout" near the end of the session his voice was shredded. He rallied by gargling milk and swallowing cough drops before nailing the song in just two takes. He was unhappy with how his voice sounded, but the raw sound is part of what makes the track so memorable.
