She also released "Shakin' Things Up" in 1997. It featured the top-ten hit "Go Away" and the top-20 single "One of Those Nights Tonight", but the following singles "I'm Not That Easy to Forget" and "You Think He'd Know Me Better" both failed to make top 40. Also included on the album was a cover of The Shirelles' "Will You Love Me Tomorrow". Morgan held her first co-production credit on the album, doing so with Stroud; backing vocalists on the album included John Cowan, Vern Gosdin, and Randall. Tom Roland of "The Tennessean" considered the album her strongest since "Something in Red", saying that it "combines a commanding, upbeat attitude with a few moments of subtle disturbance. And does so flawlessly." Remz highlighted the vocal performance on the Shirelles cover and the single "One of Those Nights Tonight" in particular, while calling the Bill Anderson composition "I've Enjoyed as Much of This as I Can Stand" the strongest song. "Shakin' Things Up" also earned a gold certification. Another album, "Secret Love", followed in 1998. This album was composed entirely of cover songs dating largely from the 1940s and 1950s, and produced no singles. Morgan dedicated the album to her father, whom she claims introduced her to such music. Among the songs covered were "Fly Me to the Moon", "I've Got the World on a String", and "Good Morning Heartache". For this album, Landis returned to production duties, while musical accompaniment was largely handled by pianist Beegie Adair and the Nashville String Machine, a session string ensemble. Morgan performed ten concerts in 1998 which promoted the album, with Adair and a small orchestra accompanying her. Charlotte Dillon of AllMusic wrote that "her voice and emotional delivery are up to the test, even for old ballads and standards", while Nash found her delivery "overly dramatic".
