Dion, 56, announced in December 2022 that she was taking time off from professional commitments to focus on her health after revealing her diagnosis. At the time, she said the condition did not allow her “to sing the way I’m used to.” The last time the “My Heart Will Go On” singer performed live was in March 2020, in New Jersey. Lady Gaga kicked off the opening Olympics event with a performance along the Seine river of “Mon truc en plume,” by Zizi Jeanmaire, France’s leading lady of Music Hall performances in the 1950s.
