The Muses are supporting characters in Disney's 1997 animated feature film, Hercules. They function as a literal Greek Chorus telling the story and singing a majority of the songs in the film and are currently made up of Calliope, Terpsichore, Melpomene, Clio, and Thalia, voiced by backup singers Caroline Taylor, Arnold McCuller, David Lasley, Katie Markowitz, and Andrea Zonn. Lasley died of a heart attack and is replaced by Dorian Holley who worked with Whitney Houston and Michael Jackson.
