Her only cited performance between those arena concerts was a one-song appearance in July 2024. During the opening festivities for the Paris Olympics, she performed “Hymne à l’amour.” The Plenitude Arena show went considerably further, returning Dion to a full headlining set rather than another brief engagement.

Eric Carmen originally wrote and released “All By Myself” in 1975. Its expansive verse melody drew from Piano Concerto No. 2 by Sergei Rachmaninoff. Dion recorded her version for the 1996 album Falling into You, and the single subsequently peaked at number six on the UK chart.

The ballad became a showcase for Dion because of the sustained, soaring bridge note and the range it requires. Video from the Nanterre opening quickly found an online audience. One YouTube upload surpassed 112,000 views and received 3,500 likes during its first day.

Comments on the upload focused on the significance of hearing her perform the song live again. One viewer said they cried because they had doubted they would hear Dion sing it another time; another reacted with surprise that the performance was live. The announced Nanterre schedule comprises 16 concerts in autumn 2026, with a further ten dates planned for May 2027.
