Answer by taking a quote from the following article:

Oingo Boingo was an American new wave band, best known for their hits "Dead Man's Party" and "Weird Science". They are noted for their high energy live concerts, movie soundtrack contributions, and their mixture of genre, which can be described as including ska, pop, rock, and world music. The band was founded in 1972 as The Mystic Knights of the Oingo Boingo, a performance art group. The band was led by songwriter/vocalist Danny Elfman, who has since achieved success as a composer for film and television.

The Mystic Knights of the Oingo Boingo, formed in late 1972 by Richard Elfman, was a musical theater troupe in the tradition of Spike Jones and Frank Zappa, performing an eclectic repertoire ranging from Cab Calloway covers to instrumentals in the style of Balinese gamelan and Russian ballet music. The name was inspired by a fictional secret society on the Amos 'n' Andy TV series called The Mystic Knights of the Sea. Most of the members performed in whiteface and clown makeup, and a typical show contained music ranging from the 1890s to the 1950s, in addition to original material. This version of the band employed as many as 15 musicians at any given time, playing over 30 instruments, including some instruments built by band members. While this Richard Elfman-led incarnation of the group performed live, it did not issue any recordings. As Richard Elfman's interest shifted to filmmaking, he passed leadership of the band to younger brother Danny Elfman, who had recently returned from spending time in Africa playing violin and studying percussion instruments. They gained a following in Los Angeles, and appeared as contestants on The Gong Show in 1976, winning the episode they appeared on with 24 points out of a possible 30. The Gong Show presentation included an accordion, a purple dragon and a gaseous rocket-man. Later in 1976, The Mystic Knights of the Oingo Boingo released a doo-wop styled novelty single about kidnapped heiress Patty Hearst entitled "You Got Your Baby Back". Both this track and the B-side "Ballad of the Caveman" were written and sung by Danny Elfman. They were featured in the 1976 Martin Brest film Hot Tomorrows; performing the songs St. James Infirmary and 42nd Street. The band appeared as extras in hallucinatory sequences in the 1977 movie I Never Promised You a Rose Garden. When the group began to move away from its cabaret style towards a more pop/rock format, Richard Elfman made a film based on the band's stage performance, Forbidden Zone, which was released in 1980 and filmed in black and white with a cast mostly made up of band members and friends. In one scene, Danny, as Satan, sings a version of Calloway's "Minnie the Moocher" with modified lyrics integrated into the plot of the film. In another, Richard sings the 1920s novelty song "The Yiddishe Charleston". The movie attained cult status and provided a springboard for the film and music careers of Richard and Danny.
