One is the Bee Gees’ eighteenth studio album (sixteenth worldwide), released in April 1989 (August 1989 in the United States).
After the European success of their previous album, E.S.P., the Gibb brothers began to work on the One album in early 1988. In March, their brother Andy suddenly died and the Bee Gees took a break until November when they returned to the studio to complete the album. The style of One was more melancholic than E.S.P., and heavily influenced by the loss of their brother. The album was dedicated to Andy and the song Wish You Were Here was written as a tribute to him.
The album was co-produced with Brian Tench who had worked with them on the previous album.
