LONDON.- A lined sheet torn from John Lennon’s High School detention book, shining a light on the musician’s mischievous schooldays, will be offered at Sotheby’s London auction on Tuesday 29th September with an estimate of £2,000-3,000.

Inscribed at the top with the pupil’s surname "Lennon", the page records the 29 occasions between 9 September 1955 and 11 July 1956 that he was sent to detention at Quarry Bank High School in Allerton, Liverpool. The frequent entries on this sheet from six different teachers reveal that John Lennon’s rebellious nature and irreverence for authority were well established traits of his character even at the age of fifteen.

On one day - 12 September 1955 - Lennon received no fewer than five separate detentions from two different teachers beginning with: "No Hwk" [homework] and continuing with ..."Impertinence"..."Talk after 2 warnings" and "Further talk". John’s lack of homework is reported on three further occasions, other misdemeanours include: "Groaning at me...", "Nuisance in class" (mentioned four times), "silly conduct", "Foolish remarks", "Disturbance", "Inattention", "Not wearing school cap", "Very late" and "Failing to report for class detention..."

According to the vendor, this page came from a book that was rescued from a bonfire at Quarry Bank High School in the late 1970s. During one summer holidays, a member of staff had been instructed to clear out a storage room and to burn all the redundant old books. He spotted the name "Lennon" at the top of some of the pages in one and tore them out. Apparently a number of the other pages he saved were lost or destroyed in an accident at a later date, and this is one of a few to survive.

The page is accompanied by a letter from Lennon’s school friend Pete Shotton who describes the musician as his "closest childhood friend". From an early age they were "almost inseparable, to the extent that John referred to us as Shennon and Lotton". Both started at Quarry Bank High School in September 1952. Shotton describes how as classmates for five years, they spent most of their time fooling around and receiving frequent detentions.

Alongside over 100 other works from Sotheby’s 29 September “Rock & Pop” sale, the detention sheet will be on public exhibition at Sotheby’s 34-35 New Bond Street, London, from 24th to 28th September 2015.

Sale highlights include the 1962 contract that cemented the relationship between Beatles and Brian Epstein, Bob Dylan’s typewritten lyrics for his revolutionary song ‘A Hard Rain’s A-Gonna Fall’ and the grand piano played by ABBA on their most celebrated songs.

Visitors to the exhibition will be able to explore musical instruments, handwritten lyrics, stage costumes, historic photographs and personal effects relating to the greats of Rock and Pop while listening to the sounds that made them famous. Beats by Dr. Dre headphones will be installed at listening stations throughout the gallery, allowing visitors to immerse themselves in the music and bring these iconic objects to life.
