Some context: Rhapsody in Blue is a 1924 musical composition by American composer George Gershwin for solo piano and jazz band, which combines elements of classical music with jazz-influenced effects. Commissioned by bandleader Paul Whiteman, the composition was orchestrated by Ferde Grofe several times, including the original 1924 scoring, "theater orchestra" setting published in 1926, and the symphony orchestra scoring published in 1942, though completed earlier. The piece received its premiere in the concert, An Experiment in Modern Music, which was held on February 12, 1924, in Aeolian Hall, New York, by Whiteman and his band with Gershwin playing the piano. The editors of the Cambridge Music Handbooks opined that "The Rhapsody in Blue (1924) established Gershwin's reputation as a serious composer and has since become one of the most popular of all American concert works."
Rhapsody in Blue premiered in an afternoon concert on Tuesday, February 12, 1924, held by Paul Whiteman and his band Palais Royal Orchestra, entitled An Experiment in Modern Music, which took place in Aeolian Hall in New York City. Many important and influential composers of the time such as John Philip Sousa and Sergei Rachmaninoff were present. The event has since become historic specifically because of its premiere of the Rhapsody. The purpose of the experiment, as told by Whiteman in a pre-concert lecture in front of many classical music critics and highbrows, was "to be purely educational". It would "at least provide a stepping stone which will make it very simple for the masses to understand, and therefore, enjoy symphony and opera". The program was long, including 26 separate musical movements, divided into 2 parts and 11 sections, bearing titles such as "True form of jazz" and "Contrast: legitimate scoring vs. jazzing". Gershwin's latest composition was the second to last piece (before Elgar's Pomp and Circumstance March No. 1). Many of the numbers sounded similar and the ventilation system in the concert hall was broken. People in the audience were losing their patience, until the clarinet glissando that opened Rhapsody in Blue was heard. The Rhapsody was performed by Whiteman's band, with an added section of string players, and George Gershwin on piano. Gershwin decided to keep his options open as to when Whiteman would bring in the orchestra and he did not write down one of the pages for solo piano, with only the words "Wait for nod" scrawled by Grofe on the band score. Gershwin improvised some of what he was playing, and he did not write out the piano part until after the performance, so it is unknown exactly how the original Rhapsody sounded. The opening clarinet glissando came into being during rehearsal when; "... as a joke on Gershwin, [Ross] Gorman (Whiteman's virtuoso clarinettist) played the opening measure with a noticeable glissando, adding what he considered a humorous touch to the passage. Reacting favourably to Gorman's whimsy, Gershwin asked him to perform the opening measure that way at the concert and to add as much of a 'wail' as possible."

Some context: Amon was born in Bulls, and attended Wanganui Collegiate School. He was the only child of wealthy sheep-owners Ngaio and Betty Amon. He learned to drive at the age of six, taught by a farm worker on the family farm. On leaving school, he persuaded his father to buy him an Austin A40 Special, which he entered in some minor local races and hillclimbs along with practice on the family farm.
After his retirement from F1, Amon dedicated himself to running the family farm in New Zealand's Manawatu District for many years. After retiring from farming, he lived in Taupo in New Zealand's North Island. In the early 1980s he became more well known in New Zealand from test-driving vehicles on the TV motoring series Motor Show and later consulted for Toyota New Zealand, tuning the 1984 Toyota Corolla and subsequent cars for sale there. He also appeared in TV commercials for the company, where much was made of the acclaim he won from Enzo Ferrari. Amon participated in the 2004 EnergyWise Rally where he won ahead of Brian Cowan. Amon drove a Toyota Prius for the event. Amon was involved in the design of the upgraded Taupo Motorsport Park circuit, used for the New Zealand round of the 2006-07 A1 Grand Prix season in January 2007. At the New Zealand Festival of Motor Racing in 2011, Amon's life and career were honoured with a selection of his cars being driven and also used the event to raise funds for the Bruce McLaren trust. Amon was also honoured at the festival in January 2013. Amon died in Rotorua Hospital on 3 August 2016, aged 73, of cancer. He was survived by his wife (they married in 1977) their three children and their grandchildren. One of his sons, James, is a qualified High Performance personal trainer. He trained Central Districts Stags cricket team, and was revealed to be Brendon Hartley's personal trainer.
