- 2023 September 30, Alexis Petridis, “U2 review – an utterly astonishing, admirably raw Vegas extravaganza”, in The Guardian‎^[1], London:
  On the most prosaic level, there’s the section in the show when what appears to be a giant rope made of knotted sheets ascends to the roof and transforms itself into a swing. Bono selects a fan from the front row in an echo of U2’s fabled Live Aid performance, seats them in the swing and pushes them out over the audience: with the best will in the world, this seems less like stagecraft than an injury lawsuit waiting to happen.
