This still boggles my mind. How could HDH erase their vocals without doing at least a rough mix? Even on an acetate. I highly doubt they sounded bad. Norman Whitfield did a mono mix of "The Nitty Gritty" before dubbing them over with Gladys Knight and the Pips. Other songs that come to mind include Marvin's "Dancing In The Street" and the Marvelettes' "Tear It On Down," both erased and lost to time because they weren't mixed.
