Cucumber Castle is the seventh studio album by the Bee Gees, released in April 1970. It was produced by Barry Gibb, Maurice Gibb, and Robert Stigwood. It consists of songs from their television special of the same name, which was named after a song on their 1967 album Bee Gees' 1st. Cucumber Castle is the only Bee Gees album not to feature any recorded contributions from Robin Gibb, as he had left the group before the album was recorded. (He did receive co-composer credit on one track, which was written before his departure.)
