Emotion is stylistically influenced by its co-writer and co-producer Barry Gibb of The Bee Gees, who also sang harmonies on the record.
An early Samantha Sang single recorded in London in 1969 had two other ‘songs The Bee Gees gave away’, The Love Of A Woman and Don’t Let It Happen Again, both by Barry & Maurice Gibb. (Single on Parlophone, UK and Atco, USA, produced by Barry Gibb. More details at Joseph Brennan’s Gibb Songs website.)
On You Light Up My Life, a 1978 album by the enduring romantic pop and jazz singer (b. 1935). Also on the album is a version of The Bee Gees hit How Deep Is Your Love.
