[8][9][10] "Kiss Me the Way You Did Last Night" and "The Uninvited Guest" are outtakes from Made in America,[11][12] the studio album released in 1981 and the last completed during Karen's lifetime.

As Karen's cozy contralto pulses through the come-hither "Lovelines," the hearth-warm "If We Try" (both written by Rod Temperton, whose credits also include "Rock With You" and "Thriller") and the saltier "If I Had You," her vocals come damn close to soulful.

[5] In their review of the album, Billboard stated that "one listen and it's clear that no one - the closest is Gloria Estefan - has filled the void left after Karen's death in 1983.

There's a good reason why some of the syrupy material was never released, but other tracks, like first single "If I Had You," the classic "When I Fall In Love," and "Where Do I Go From Here," instantly recall why the duo was one of the most successful of the '70s."

[14] Allmusic noted that "When I Fall in Love" brings a tear to the eye as it captures that indefinable and completely unique quality that Karen brought to each song she sang.
