Oceán also worked regularly with Petr Hons, who was unofficially part of the band and who wrote most of their song lyrics.
"Lék světu / Jeden den" followed in 1989, and the same year the band's idols, British synth-pop duo Erasure, visited Prague on their European tour.
From December 1989 to January 1990, Oceán supported Erasure on their UK & Ireland tour, which turned out to be a big success for the Czech band.
The band experienced a steep rise in popularity and went on to record several music videos in Greece.
At the beginning of 1992, their maxi single "Haifa" came out, containing four remixes of songs from the album Pyramida snů, and in the same year, the compilation 2 1/2 was released, featuring unreleased demos and other tracks.
