The last chord of the "Sgt. Pepper" reprise segues amid audience applause to acoustic guitar strumming and the start of what Moore calls "one of the most harrowing songs ever written". "A Day in the Life" consists of four verses by Lennon, a bridge, two aleatoric orchestral crescendos, and an interpolated middle part written and sung by McCartney. The first crescendo serves as a segue between the third verse and the middle part, leading to a bridge known as the "dream sequence". Lennon drew inspiration for the lyrics from a "Daily Mail" report on potholes in the Lancashire town of Blackburn and an article in the same newspaper relating to the death of Beatles friend and Guinness heir Tara Browne.
