And as u can see here, the notes on the live version of BOMT where different from the studio version, still, their editing was so lazy she has her mouth open for nothing (she was singing, or "singing" live on that part) , and once she closes her mouth, the album version notes come from nowhere...
They not only took everything she sang (or pretended she sang) out, they also put the studio version even where it didn't fit... crapy, crapy work...
