Question: Who was the choreographer of Alice Cooper's Welcome to My Nightmare?
Sentence (from "Welcome to My Nightmare (film)"): Whilst in the past the Alice Cooper stage show was semi-improvisatory, with confrontational elements of violence and satire (see "Good to See You Again, Alice Cooper"), the new production was purely horror-themed and professionally choreographed and performed to the split second (Winters had a long history of choreographing and directing big celebrity films, stage and TV shows starring in the cast of West Side Story and choreographing 4 films with Elvis Presley and 5 films with Ann-Margret).
Relevant evidence: No
