"Tomorrow Tomorrow" is a song by the Bee Gees written by Barry and Maurice Gibb. The song was originally intended to be recorded by Joe Cocker. It was the first Bee Gees single released after Robin Gibb had quit the group which was now down to a trio featuring Barry Gibb, Maurice Gibb, and drummer Colin Petersen.

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.
