The opening act was a razor
Every show on Bowie's 1976 Isolar tour began with a screening of Un Chien Andalou. He walked on stage as it ended.
Buñuel and Salvador Dalí made Un Chien Andalou to shock, and its opening scene, a razor drawn across an eye, still does.
In 1976 Bowie was touring Station to Station as the Thin White Duke. The shows began without an introduction. The film played, and Bowie appeared the moment it finished. The 1978 tour dropped it.
