The album's first single, "Feel", written by Williams and Chambers, was recorded as a demo. When they started working on the album and were trying to re-record the vocals, Williams felt unsatisfied with it, so he decided to include the demo version and then release it as the first single. When the single was released in late 2002, it became Williams' biggest international hit, going number one in The Netherlands and Italy, as well as reaching the top ten in many European countries. When Williams' fifth studio album, Escapology, was released in late 2002, it hit number one in at least 10 countries around the world. In the United States, however, it failed to make such an impact. Escapology sold almost 2 million copies by the end of 2003 in the United Kingdom. On 1–3 August 2003, Williams played three consecutive concerts at Knebworth to 125,000 people each night, making it the biggest event in UK music history. Memorable performances included “Come Undone” where he interjected with “Britain, I’m Your Son”, and further interacted with the audience when he brought a girl up on stage. In October 2003, Williams released a live album of the concerts, Live at Knebworth.
