Lady Gaga's performance at the Olympics was prerecorded. During an interview with Variety, Paris Olympics Director of Dance Maud Le Pladec revealed that Lady Gaga's Olympics opening ceremony performance was actually happened earlier than televised.
He explained, “Unfortunately, it was the only (performance) that, for safety reasons, we had to prerecord late in the afternoon, once we knew for sure that it was going to rain. We had minute-by-minute updates; we had never watched the weather forecast so closely in our lives."
"We assessed that it was going to be too dangerous for performers, even with a few drops of rain. (Gaga) wanted to do it absolutely, so we preferred to prerecord it rather than cancel it."
"The soil at the location of the performance "would have been slippery," and the wet conditions would not have been ideal for Gaga, who was wearing heels".
"We had to be extremely cautious".
