My only concern is that it might not be what she really plays...just the vocal line and bass
That's the common concern with sheet music books - they are not always accurate. They usually base the notes on whatever is dominant on the song, sometimes instruments other than the piano, which is what we're really after.
That's true, like the guitar, violins, violas, cellos, double bass or the bass guitar, y'know, your typical stringed instruments. I reckon they do this just in case someone wants the full arrangement of the song, but that's not what many of us are looking for. The (sheet music) publishing companies -- especially Hal-Leonard -- not only do this w/ VC, but w/ other artists as well. Many times the piano has to be the only instrument playing (like in 'Wanted') in order to get the actual keyboard/piano arrangement, but even w/ that there's discrepancies and those of us who go by ear have the challenge of correcting those mistakes.
