During her career, Dion recorded with opera singers
Luciano Pavarotti on "I Hate You Then I Love You" in 1997 and
Andrea Bocelli on "
The Prayer" in 1998. In 2005, she collaborated with the classical crossover group
Il Divo on "I Believe in You". The song was written by
Jörgen Elofsson,
Per Magnusson,
David Kreuger, and Matteo Saggese, with English lyrics.
Luc Plamondon, who had worked with Dion on her 1991 album
Dion chante Plamondon, wrote the French text. The English-French duet, titled "I Believe in You (Je crois en toi)", appeared on Dion's
On ne change pas in September 2005 and on Il Divo's
Ancora in November 2005. On Dion's album, the line "Someday I'll find you" is sung by Swiss tenor
Urs Buhler, while on Il Divo's album it is performed by Spanish baritone
Carlos Marín. This difference results from a swap of vocal lines, including part of the harmony in Dion's second verse. An English-only version was completed but never released; however, Il Divo performed it in concert, with tenor
David Miller singing Dion's parts. "I Believe in You (Je crois en toi)" was issued to US radio on 23 January 2006. The commercial single followed on 1 May 2006 in France and on 12 May 2006 in Switzerland. It was also sent to Canadian radio in May 2006. On 20 May 2006, the duet was included on the official
2006 FIFA World Cup album,
Voices from the FIFA World Cup. == Critical reception ==
