Coldplay have been performing lots of covers and bringing out guests for their tour dates this summer — at Glastonbury, in Copenhagen and Philadelphia, and with Marty McFly — and at last night’s show at the Rose Bowl in California, they brought out James Corden to sing “Nothing Compares 2 U.” It was also the late-night show host’s birthday (well, technically, it’s today), so the band sang “Happy Birthday” to him and gave him a cake after they were done with the cover.
