Four session musicians were brought in to play the French horn parts for the song "Sgt Pepper's Lonely Hearts Club Band". "I wrote out phrases for them based on what Paul McCartney was humming to us and George Martin. All four Beatles were there but only Paul took an active interest in our overdub." (John Burden, The Complete Beatles Recording Sessions). After the brass overdub was complete, Paul recorded lead guitar onto the song. Mixing of "Lucy in the Sky With Diamonds." (Leslie Bryce)
