"Eternity"/"The Road to Mandalay" is the fifth single from Robbie Williams' 2000 Sing When You're Winning album, released in July 2001. "Eternity" does not appear in the album but it was later included on Williams' Greatest Hits album. The lyrics of "Eternity" were written as a tribute to Williams' close friendship with Geri Halliwell and was the 20th best selling single of 2001 in the UK. 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.
