Alfred Matthew "Weird Al" Yankovic is an American musician, comedian, and actor. He is best known for writing and performing comedy songs that often parody specific songs by contemporary musicians. He also performs original songs that are style pastiches of the work of other acts, as well as polka medleys of several popular songs, most of which feature his trademark accordion.

Barret Eugene Hansen, known professionally as Dr. Demento, is an American radio broadcaster and record collector specializing in novelty songs, comedy, and strange or unusual recordings dating from the early days of phonograph records to the present. Hansen created the Demento persona in 1970 while working at Pasadena, California station KPPC-FM. He played "Transfusion" by Nervous Norvus on the radio, and DJ "The Obscene" Steven Clean said that Hansen had to be "demented" to play it, and the name stuck. His weekly show went into syndication in 1974 and was syndicated by the Westwood One Radio Network from 1978 to 1992. Broadcast syndication of the show ended on June 6, 2010, but the show continues to be produced weekly in an online version.
