While the CD cannot be an exact replica of the Michael Buble version, it's close enough that I find it easy to practice for the wedding where I will sing it in four weeks. I like that there are three vocal ranges. (I plan to sing the baritone version.) I suppose, for copyright purposes, Stevie Wonder's original lyrics had to be included. I think for a novice this could prove confusing because there are more words in the lyrics than are needed in the song itself. Overall, though, it's a good CD, it arrived in good shape, and even the plastic cover wasn't cracked. I'm pleased.
