Eternity (Robbie Williams song)

"Eternity" is a song by English singer-songwriter Robbie Williams. It was written by Williams along with Guy Chambers, while production was overseen by Chambers and Steve Power. "Eternity" does not appear on his third studio album, Sing When You're Winning (2000) but was later included on Williams' Greatest Hits album in 2004. The lyrics of "Eternity" were written as a tribute to Williams' close friendship with Geri Halliwell. Brian May of Queen plays electric guitar on the track.

Released on 9 July 2001 as a double A-side with "The Road to Mandalay", the single became the 20th-most-successful hit of 2001 in the United Kingdom, topping the country's singles chart, and also peaked at number two in Ireland. "Eternity" as a solo single reached number one in New Zealand and became a top-10 hit in eight other countries. Though "Eternity" never appeared on a Robbie Williams studio album, a comedic snippet of the song can be heard in "Outtakes", a hidden track on Swing When You're Winning.
