The Bee Gees were three brothers - Barry, Robin and Maurice Gibb. They wrote this song after getting in a few arguments and realizing the power of words, how they can make you happy or sad.
This was written for a movie called The Mini-Affair. In England, the movie was titled The Mini Mob.
Barry was the only Gibb to sing on this. It was the first Bee Gees single where only one brother sang.
A cover version by Rita Coolidge hit #25 in the UK in 1978. In 1996 a cover version by Irish boy band Boyzone topped the UK chart. Maurice Gibb declared it the best ever cover of a Bee Gees song.
The Bee Gees became icons of the disco era, but before they started singing dance songs in high falsetto voices, most of their songs were mellow ballads with lush arrangements like "Words."
This song was originally written for Cliff Richard, but he never got around to recording it because he wasn't making an album at the time. Rather than wasting the song, The Bee Gees decided to record it themselves.
Elvis Presley performed the song live as part of his concerts in the late '60s and early '70s. His version can be found on the 1970 live album, Elvis in Person at the International Hotel.
