"Heart and Soul" by British pop band T'Pau, Featuring Carol Decker performing overlapping lyrics, is from the group's 1987 debut album Bridge of Spies.
The song is notable for its usage of various vocal overdubs. This makes the song, in its initial studio form, impossible to perform live without additional backup singers.
