Madonna opened the World Cup halftime show with her 2000 dance-pop hit “Music,” joined by star Brazilian soccer players of yesteryear, Ronaldo and Ronaldinho. Sunday's show started with an apparently prerecorded piece in a roller rink before she rode into the stadium on a dune buggy. Venezuelan conductor Gustavo Dudamel led an orchestra through the White Stripes’ sporting anthem “Seven Nation Army,” while Animal and other Muppets bopped and shook. K-pop sensations BTS took to the field in red and black moments later singing “Dynamite.” There was also Justin Bieber, “Ted Lasso” characters and, of course, “Dai Dai.”
