You can't accuse Sheryl Crow of lip-synching, but you can say her memory sucks -- because she flat out forgot the lyrics to one of her biggest hits during a concert.
In the video ... Crow trips over the lyrics, but like a pro, she keeps going and asks the crowd ... "Oh, what's the words?" Then adds, "It's live! Nothing on tape here!"
Crow smiled and gave the awesome excuse, "I'm 50 what can I say! My brain has gone to s**t!"
And since the song is now looped in your head ... yours has too. Thanks, Sheryl.
