After recovering from her first surgery, Terrell returned to Hitsville studios in Detroit and recorded "You're All I Need to Get By". Both that song and "Ain't Nothing Like the Real Thing", reached No. 1 on the R&B charts. Despite Terrell's optimism, her tumor worsened, requiring more surgeries. By 1969, Terrell had retired from live performances as she had been ordered by doctors not to perform due to her tumors. Motown issued Terrell's first and only solo album, "Irresistible", in early 1969. Terrell was too ill to promote the recordings. There was no new repertoire on the album: all tracks had been recorded earlier and subsequently shelved for some time.
