I'm only rating this on the song "Heaven Must Be Missing An Angel," which I purchased to create an anniversary compilcation CD. I don't know the original source of this version, but it is at a much faster tempo than the longer version on "Anthology". To my memory, the "Anthology" version is what I heard in the discos of the 70's. I decided I wanted the "Anthology" version for my collection. Be sure to listen to both samples before makeing your purchasing decision.
