Task: Question Generation
Input (English): Passage: At age 15, Lennon formed a skiffle group, the Quarrymen. Named after Quarry Bank High School, the group was established by Lennon in September 1956. By the summer of 1957, the Quarrymen played a "spirited set of songs" made up of half skiffle and half rock and roll. Lennon first met Paul McCartney at the Quarrymen's second performance, which was held in Woolton on 6 July at the St Peter's Church garden fête. Lennon then asked McCartney to join the band.McCartney said that Aunt Mimi "was very aware that John's friends were lower class", and would often patronise him when he arrived to visit Lennon. According to McCartney's brother Mike, their father similarly disapproved of Lennon, declaring that Lennon would get his son "into trouble". McCartney's father nevertheless allowed the fledgling band to rehearse in the family's front room at 20 Forthlin Road. During this time, Lennon wrote his first song, "Hello Little Girl", which became a UK top 10 hit for the Fourmost in 1963.McCartney recommended his friend George Harrison to be the lead guitarist. Lennon thought that Harrison, then 14 years old, was too young. McCartney engineered an audition on the upper deck of a Liverpool bus, where Harrison played "Raunchy" for Lennon and was asked to join. Stuart Sutcliffe, Lennon's friend from art school, later joined as bassist. Lennon, McCartney, Harrison and Sutcliffe became "The Beatles" in early 1960. In August that year, the Beatles were engaged for a 48-night residency in Hamburg, in West Germany, and were desperately in need of a drummer. They asked Pete Best to join them. Lennon's aunt, horrified when he told her about the trip, pleaded with Lennon to continue his art studies instead. After the first Hamburg residency, the band accepted another in April 1961, and a third in April 1962. As with the other band members, Lennon was introduced to Preludin while in Hamburg, and regularly took the drug as a stimulant during their long, overnight performances.
Output (English): What is the first name of the person who said that Aunt Mimi "was very aware that John's friends were lower class?"?
