On this day in 1967 – Working on sessions for the new Beatles album Sgt. Pepper at Abbey Road studios in London, John Lennon recorded his lead vocal for ‘Good Morning Good Morning’, and Paul McCartney added a lead guitar solo to the track. Lennon had decided he wanted to end the song with animal sound effects, and asked that they be sequenced in such a way that each successive animal was capable of scaring or eating the preceding one.
