"Live at Knebworth" is Robbie Williams' first live album, recorded during three monumental concerts at Knebworth, England, from August 1 to 3, 2003. This event drew an astonishing 375,000 fans, marking it as the largest music event in British history at the time.
The album quickly became the second fastest and biggest-selling live album in the UK, following the success of his former band Take That’s The Greatest Day – Take That Present: The Circus Live. It achieved 2× Platinum certification from the IFPI, signifying over 2 million copies sold.
Accompanying the live album, the DVD titled What We Did Last Summer captured the highlights of the Knebworth performances. It resonated with audiences, selling 350,000 copies in the UK alone and surpassing the album's sales in Australia, where it sold 165,000 copies.
A highlight of the Knebworth shows was the reunion of Williams with his former Take That bandmate Mark Owen, who joined him on stage to perform "Back for Good." This marked their first collaboration since the band's split in 1996 and reignited interest in Owen's solo career.
