"The Lady Is a Tramp" is a show tune from the 1937 Rodgers and Hart musical Babes in Arms in which it was introduced by former child star Mitzi Green. This song is a spoof of New York high society and its strict etiquette (the first line of the verse is significant: "I get too hungry for dinner at eight..."). It has become a popular standard.

Early recordings from 1937 include one by Tommy Dorsey and His Orchestra, (featuring Edythe Wright on vocals), Midge Williams and Her Jazz Jesters, Sophie Tucker, and Bernie Cummins on the Vocalion records label (#3714).

Lena Horne recorded the song with the Metro-Goldwyn-Mayer Studio Orchestra on March 30, 1948. Her performance appeared in the film, Words and Music, a fictionalized biography of the partnership of Rodgers and Hart.

It was recorded by Frank Sinatra and Ella Fitzgerald in 1950s and Shirley Bassey in the 1960s, becoming a signature song for each of them. Sinatra also sang it in the film Pal Joey.

In later years, as heard on the first Duets album, Sinatra would often alter the title lyric to "...That's why this chick is a champ.". Fitzgerald would in turn alter the lyrics to praise Sinatra or Sidney Poitier "...and for Frank Sinatra I whistle and stamp!". She and Sinatra sang the song as a duet on the 1967 television special A Man and His Music + Ella + Jobim.

Anthony Dominick Benedetto, better known as Tony Bennett (born August 3, 1926), is an American singer of popular music, standards, show tunes, and jazz. Bennett is also a serious and accomplished painter, having created works — under the name Benedetto — that are on permanent public display in several institutions. He is the founder of Frank Sinatra School of the Arts in New York City.

Raised in New York City, Bennett began singing at an early age. He fought in the final stages of World War II as an infantryman with the U.S. Army in the European Theatre. Afterwards, he developed his singing technique, signed with Columbia Records, and had his first number one popular song with "Because of You" in 1951. Several top hits such as "Rags to Riches" followed in the early 1950s. Bennett then further refined his approach to encompass jazz singing. He reached an artistic peak in the late 1950s with albums such as The Beat of My Heart and Basie Swings, Bennett Sings. In 1962, Bennett recorded his signature song, "I Left My Heart in San Francisco". His career and his personal life then suffered an extended downturn during the height of the rock music era.

Stefani Joanne Angelina Germanotta (/ˈstɛfəniː dʒʌrməˈnɑːtə/ STE-fə-nee jurr-mə-NAH-tə; born March 28, 1986), known by her stage name Lady Gaga, is an American singer and songwriter. Born and raised in New York City, she primarily studied at the Convent of the Sacred Heart and briefly attended New York University's Tisch School of the Arts before withdrawing to focus on her musical career. She began performing in the rock music scene of Manhattan's Lower East Side, and was signed with Streamline Records by the end of 2007. During her employment as a songwriter for the record company, her vocal abilities captured the attention of recording artist Akon, who signed her to his label Kon Live Distribution.

Lady Gaga came to prominence as a recording artist following the release of her debut album The Fame (2008), which was a critical and commercial success that topped charts around the world and included the international number-one singles "Just Dance" and "Poker Face". After embarking on the The Fame Ball Tour, she followed the album with The Fame Monster (2009), which spawned the worldwide hit singles "Bad Romance", "Telephone" and "Alejandro". The album's success allowed her to embark on the eighteen-month long Monster Ball Tour, which later became one of the highest-grossing concert tours of all time. Her most recent album Born This Way (2011) topped the charts of most major markets and generated more international chart-topping singles, including "Born This Way", "Judas" and "The Edge of Glory". Besides her musical career, she involves herself with humanitarian causes and LGBT activism.

Francis Albert "Frank" Sinatra,  /sɨˈnɑːtrə/, (December 12, 1915 – May 14, 1998) was an American singer and film actor.

Beginning his musical career in the swing era with Harry James and Tommy Dorsey, Sinatra became an unprecedentedly successful solo artist in the early to mid-1940s, after being signed to Columbia Records in 1943. Being the idol of the "bobby soxers", he released his first album, The Voice of Frank Sinatra in 1946. His professional career had stalled by the 1950s, but it was reborn in 1953 after he won the Academy Award for Best Supporting Actor for his performance in From Here to Eternity.

He signed with Capitol Records in 1953 and released several critically lauded albums (such as In the Wee Small Hours, Songs for Swingin' Lovers, Come Fly with Me, Only the Lonely and Nice 'n' Easy). Sinatra left Capitol to found his own record label, Reprise Records in 1961 (finding success with albums such as Ring-a-Ding-Ding!, Sinatra at the Sands and Francis Albert Sinatra & Antonio Carlos Jobim), toured internationally, was a founding member of the Rat Pack and fraternized with celebrities and statesmen, including John F. Kennedy. Sinatra turned 50 in 1965, recorded the retrospective September of My Years, starred in the Emmy-winning television special Frank Sinatra: A Man and His Music, and scored hits with "Strangers in the Night" and "My Way".

Ella Jane Fitzgerald (April 25, 1917 – June 15, 1996), also known as the "First Lady of Song", "Queen of Jazz", and "Lady Ella", was an American jazz and song vocalist. With a vocal range spanning three octaves (D♭3 to D♭6), she was noted for her purity of tone, impeccable diction, phrasing and intonation, and a "horn-like" improvisational ability, particularly in her scat singing.

Fitzgerald was a notable interpreter of the Great American Songbook. Over the course of her 59-year recording career, she was the winner of 13 Grammy Awards and was awarded the National Medal of Arts by Ronald Reagan and the Presidential Medal of Freedom by George H. W. Bush.

Fitzgerald was born in Newport News, Virginia, the child of a common-law marriage between William and Temperance "Tempie" Fitzgerald. The pair separated soon after her birth and she and her mother went to Yonkers, New York, where they eventually moved in with Tempie's longtime boyfriend, Joseph Da Silva. Fitzgerald's half-sister, Frances Da Silva, was born in 1923. She and her family were Methodists and were active in the Bethany African Methodist Episcopal Church and she regularly attended worship services, Bible study, and Sunday School.
