There’s something incredible about seeing Shawn Carter cough up a lung for Marcy as 20,000 young Britons scream along. Tonight was the fourth of five shows Jay-Z and Kanye booked at the O2 Arena, and they were in superb form. The crowd went absolutely nuts (not least when Ye made his little Wills and Kate joke four times in a row). Still more proof that hip-hop is universal, and these guys in particular are intercontinental superstars. Later this week they’re playing Zurich. The Swiss kids will probably know all the words, too.
