The tour was organized to support the highly successful fourteenth French-language and twenty-fourth studio album Sans attendre (2012), which has sold more than 1.5 million copies worldwide.

According to producer Gilbert Coullier, speaking on France Bleu 107.1, The European 'mini-tour' was originally planned to cover both the Francophone and Anglophone markets (including the UK and Germany), allowing Dion to promote her latest French and English releases simultaneously.

The Francophone part of the tour went ahead as planned, celebrating the highly successful 2012 album Sans attendre in Belgium and France.

The setlist was very similar to that of Celine... une seule fois, a special one-off outdoor show in Quebec during the summer of 2013 (see below).

Although not officially a part of the Sans attendre Tour, Dion performed for one night only in front of 42,495 spectators in Quebec City on the Plains of Abraham, on 27 July 2013.

[9] Céline... une seule fois marked Dion's second official public concert outside of Las Vegas since her second residency began in March 2011; the first was in 2012 at the Jamaica Jazz and Blues Festival.

The rest of the setlist featured the same French songs previously performed in the 2008-2009 Taking Chances World Tour (with the exception of "Et s'il n'en restait qu'une (je serais celle-là)"), as well as English selections from Dion's current Las Vegas show, Celine.

Despite the reports claiming the setlist would cover Dion's entire French career, there were no songs from the albums 1 fille & 4 types or D'elles.

At a press conference before the show, it was reported that the European Sans attendre Tour concerts in November and December 2013 would feature a similar setlist to Céline... une seule fois.

"Ce n'était qu'un rêve" was performed a cappella as an introduction, and the title track from Dion's upcoming English album, "Loved Me Back to Life", was also added at the end of the show.
