Background: 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."
Context: 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."

Background: Lane was born Morton Donald Isaacson at the Manhattan "Flower Hospital" in New York City to a Jewish father (Jacob) and a Catholic mother (Dolly), who later converted to Judaism. Jacob "Jack" Isaacson was a sergeant in the New York City Police Department (NYPD) and Dolly was a homemaker. He was raised in The Bronx, where he attended DeWitt Clinton High School and was classmates with Judd Hirsch and Garry Marshall. By his mid-teens, due to his mother's influential personality, Isaacson had decided he wanted to be in show business.
Context: After leaving college, Isaacson formed a double act with his best friend Manny Glasser called "Donny and the Duke". The duo worked in local New York nightclubs for a few months before Isaacson was drafted into the US Army at age 21. He was commissioned as an officer and served in the artillery. While in the army he formed a double act with fellow soldier Murray Levine, Isaacson usually playing the comic while his partner was the straight man. The double act went on to win the All-Army entertainment contest and earned them an appearance on The Ed Sullivan Show in 1955. One year later Isaacson won the All-Army entertainment contest again as a solo act. After his mandatory service in the army, he later toured for two years entertaining troops all over the United States. After touring the country entertaining the troops as a solo performer, Isaacson started to work his act in the New York nightclubs. It was at this time that he adopted the stage name of "Don Lane", after fellow entertainer Frankie Laine. Lane worked his act in nightclubs throughout New York, Los Angeles and the showrooms in Las Vegas. During his stint in Las Vegas, he worked alongside Wayne Newton and was often a supporting act for performers such as Sammy Davis Jr.. While in Los Angeles, Lane also worked as an actor and featured in national commercials for Coca-Cola, which Lane said "paid the bills for years". He then returned to New York and performed at weddings, nightclubs and parties. In 1964 Lane was offered a contract to be the headline act at The Dunes Nightclub in Honolulu, Hawaii. This was his first offer to become a headliner and first guaranteed contract as a solo performer. Due to the lucrative offer The Dunes Nightclub made to him, he quickly relocated to Honolulu, where he first started to enjoy success as a headline performer. It was in Hawaii that he met his first wife, Gina, who was an exotic dancer.
