Ah, bless her, she just missed her cue, which can happen to even the most professional singers, but at least if there had been a live band they would have let her catch up by playing the intro again, she had no hope with a pre-recorded backing track.
I really have to admire her for not giving up, and carrying on regardless,and by the end of the song she had caught up with the music, which is to be admired. I know she won't win, but she and her family should be proud
