Welcome to My Nightmare (film): In 1975, Alice Cooper released his first solo album, "Welcome to My Nightmare", and a huge theatrical stage show was created and put together by Winters to 'tour the album'.  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).  With the edginess removed (gone were the bloody guillotine, the spit and the skewered baby dolls, although "Only Women Bleed" presented a drunken, physically abusive side to the character), the "Welcome to My Nightmare" show was part a carefully planned move toward a more mainstream-friendly 'Alice'.
