Beaucoup Fish is the fifth album by Underworld, released in 1999. Following the huge success of the single "Born Slippy .NUXX" from its use in the film Trainspotting, Beaucoup Fish was Underworld's most anticipated release. It spawned several successful singles, including "Push Upstairs", "Jumbo" and "Moaner", which was previously used in the film Batman & Robin. It is the last studio album to feature Darren Emerson.
The album's working title was ''Tonight Matthew, I'm Going to be Underworld'', inspired by the famous catchphrase "Tonight [host name], I'm going to be...", used on the British celebrity impersonation TV programme Stars in Their Eyes. The title was changed to Beaucoup Fish ("beaucoup" being French for "much"), on the basis that the tongue-in-cheek title would be incomprehensible to listeners outside of the United Kingdom. The current title comes from a sampled voice used in "Jumbo".
