Task: Question Answering
Input (English): Passage: Brian Epstein managed the Beatles from 1962 until his death in 1967. He had no previous experience managing artists, but he had a strong influence on the group's dress code and attitude on stage. Lennon initially resisted his attempts to encourage the band to present a professional appearance, but eventually complied, saying, "I'll wear a bloody balloon if somebody's going to pay me." McCartney took over on bass after Sutcliffe decided to stay in Hamburg, and Best was replaced with drummer Ringo Starr; this completed the four-piece line-up that would remain until the group's break-up in 1970. The band's first single, "Love Me Do", was released in October 1962 and reached No. 17 on the British charts. They recorded their debut album, Please Please Me, in under 10 hours on 11 February 1963, a day when Lennon was suffering the effects of a cold, which is evident in the vocal on the last song to be recorded that day, "Twist and Shout". The Lennon–McCartney songwriting partnership yielded eight of its fourteen tracks. With a few exceptions, one being the album title itself, Lennon had yet to bring his love of wordplay to bear on his song lyrics, saying: "We were just writing songs ... pop songs with no more thought of them than that – to create a sound. And the words were almost irrelevant". In a 1987 interview, McCartney said that the other Beatles idolised Lennon: "He was like our own little Elvis ... We all looked up to John. He was older and he was very much the leader; he was the quickest wit and the smartest.". 
Question: Who said they were just writing pop songs?
Output (English): Lennon.
