Lady Gaga, Celine Dion and French-Malian singer Aya Nakamura joined dancers, an opera diva and even a heavy metal band in an opening ceremony for the Paris Olympics that sought to proudly showcase French culture. The first-ever opening ceremony held outside a stadium – on the River Seine – had to battle driving rain that cast a pallid gloom over the City of Light. Tokyo Games gold medallist in high jump Mutaz Barshim and women’s 100m sprinter Shahd Ashraf carried Qatar’s flag in the boats along the Seine River.
