 This tour saw Mercury start to wear full leather/vinyl outfits instead of glam-inspired leotards (which drew a public jibe from Rob Halford of Judas Priest) and, in keeping with a theme of their latest singles "Bicycle Race" and "Fat Bottomed Girls", a group of topless women riding bicycles sometimes appeared on stage.To some observers, there seemed to be a 'sex theme' deliberately integrated into the shows and this tour first saw the now famous Brian-Brian chant from the audience.Another unexpected feature of many shows was the requests for the seemingly inconspicuous song "Mustapha" by numerous members of the crowd.
