The song was written by composer Francesco Sartori and lyricist Lucio Quarantotto, the same writers of Bocelli's biggest hit "Con te partirò", and is among Bocelli's most popular and well-known songs.
Like "Con te partirò", the song was later recorded as a duet between Bocelli and Sarah Brightman, for her 2008 album Symphony.
It was performed as a duet with Brightman at Andrea's "Live in Tuscany" Concert.
In 2011, it was sung as a duet by Cheryl Baker of Bucks Fizz and The X Factor 2009 winner Joe McElderry on the second and final season of Popstar to Operastar.
It was later recorded solo by McElderry for his second album Classic after winning the show.
