First recorded (as a demo) by The Bee Gees (1978).
Hit versions by Samantha Sang (US #3/R&B #42/UK #11 1978), Destiny’s Child (US#10/R&B #28/UK #3 2001).
From the wiki: “‘Emotion’ was written by Barry and Robin Gibb and was originally intended for the Saturday Night Fever soundtrack. During the planning for Australian singer Samantha Sang’s recording session another Bee Gees’ song, ‘Don’t Throw It All Away’, had been planned for Sang to sing but upon arriving in Miami, Barry instead offered her a new song: ‘Emotion’. Sang recorded it in a breathy, Barry-like sound. Gibb himself provided harmony and background vocals, using his falsetto on this track.
“In 2001, ‘Emotion’ was covered by the American R&B girl group Destiny’s Child. Issued as the fourth single from their third studio album, Survivor, the song continued the group’s streak of top-ten hits in the United States, peaking at #10 on the Billboard Hot 100 on 20 November 2001. The song was heavily on radio station playlists during the aftermath of the September 11, 2001 attacks, and eventually became a tribute song to the family of the victims.”
