17 People We Really Wish Had Shown Up at the Grammys

Adele's performance of "All I Ask" was plagued with technical issues, which the singer later explained via Twitter: "The piano mics fell on to the piano strings, that's what the guitar sound was. It made it sound out of tune," she wrote. A CBS spokesperson confirmed that there was a "five-to-eight-second technical issue" and that it was "out of the network's control." Despite the hiccups, Adele powered through, but we still wish that they would have brought in some sort of audio engineer or dedicated piano mic specialist.
