LOS ANGELES (AP) — The woman who created the most popular album in the U.S. last year had a trying Grammy Awards.

Recording Academy President Neil Portnow said there was a "technical glitch" after a microphone fell into the piano during the British superstar's performance Monday of the tender "All I Ask."

The result was that the hitmaker sounded very mortal — TV audiences heard a pitchy song and saw an unsettled Adele. The singer later used the mess-up as an excuse to go get a burger.

It was one of a few episodes during the telecast that had some users of social media fuming about mismatched singers or sound problems. Even access to the live stream had reported glitches.
