Songs which appeared on the show included "Bohemian Rhapsody", "Fat Bottomed Girls", "The Show Must Go On", "Who Wants to Live Forever", and "Innuendo".

On 15 November 2009, Brian May and Roger Taylor appeared on the singing contest television show X Factor in the UK. Question: On what date did Queen's May and Taylor appear on UK X-factor?
