Robbie Williams has unveiled his long-awaited comeback single to fans, warning them to prepare for "something cosmic".
Bodies was played on radio stations around the UK from 8am but the pop star delivered it in person to The Chris Moyles Show on BBC Radio 1.
After two and a half years away from the charts, Williams announced earlier this month that he planned to release a new single and album.
The Stoke-on-Trent singer told Radio 1 listeners to be prepared for "something cosmic to happen" when the track was played.
Williams - whose arrival at the radio station's studios was met by a crowd of photographers - said: "Just be prepared for something cosmic to happen to you while this single is played. I want to be a bit Uri Geller with this as well.
"Grab a watch that has not been working for a while or a watch by the bed or an alarm clock. During the track watches will start that haven't started for a long time and alarm clocks will come to life or change the numbers."
After the song was played, Williams said he wanted to hear from anyone whose watches had started again or noticed anything "miraculous".
Bodies will be available for download on October 11 and in the shops a day later, with his album Reality Killed The Video Star out on November 9.
Williams, 35, has not released a single since She's Madonna in March 2007 or an album since Rudebox in October 2006.
The new single and album were both produced by Trevor Horn, the legendary producer who in his younger days was one half of electro-pop duo The Buggles.
