Bowie's love of acting led his total immersion in the characters he created for his music. "Offstage I'm a robot. Onstage I achieve emotion. It's probably why I prefer dressing up as Ziggy to being David." With satisfaction came severe personal difficulties: acting the same role over an extended period, it became impossible for him to separate Ziggy Stardust—and later, the Thin White Duke—from his own character offstage. Ziggy, Bowie said, "wouldn't leave me alone for years. That was when it all started to go sour ... My whole personality was affected. It became very dangerous. I really did have doubts about my sanity." His later Ziggy shows, which included songs from both "Ziggy Stardust" and "Aladdin Sane", were ultra-theatrical affairs filled with shocking stage moments, such as Bowie stripping down to a sumo wrestling loincloth or simulating oral sex with Ronson's guitar. Bowie toured and gave press conferences as Ziggy before a dramatic and abrupt on-stage "retirement" at London's Hammersmith Odeon on 3 July 1973. Footage from the final show was released the same year for the film "Ziggy Stardust and the Spiders from Mars".
