In 1970, when the Blue Notes broke up, Melvin, now aware of Pendergrass' vocal prowess, asked him to take the lead singer spot. It's no secret that Kenneth Gamble and Leon Huff wanted Marvin Junior of the Dells for their Philadelphia International Records roster. Since the Dells were signed to Chess, they were unavailable. When the gruff'n'ready vocals of Pendergrass came their way, they eagerly signed the group.
Beginning with "I Miss You," a steady stream of hit singles flowed from the collaboration of Pendergrass and Gamble & Huff: "If You Don't Know Me by Now," "The Love I Lost," "Bad Luck," "Wake Up Everybody" (number one R&B for two weeks in 1976), and two gold albums, To Be True and Wake Up Everybody.
Unfortunately, the more success the group had, the more friction developed between Melvin and Pendergrass.
