Kvitka "Kasey" Cisyk (Ukrainian: Квітка Цісик; Квітослава-Орися Цісик, Kvitka Tsisyk; April 4, 1953 – March 29, 1998) was an American coloratura soprano of Ukrainian ethnicity. Cisyk, a classically trained opera singer, achieved success in four musical genres: popular music, classical opera, Ukrainian folk music and commercial jingles for radio and TV advertisements.
Cisyk recorded her version of "You Light Up My Life" for the film of the same title (Oscar and Golden Globe Awards win in 1978), sang the "Have you driven a Ford lately?" and "You deserve a break today!" jingles, and released two critically acclaimed albums of Ukrainian songs.
