"Lost Weekend" is a song by the British pop and rock band Lloyd Cole and the Commotions, released in 1985 as the second single from their second studio album Easy Pieces.

The song was written by band members Neil Clark, Lloyd Cole and Lawrence Donegan, and produced by Clive Langer and Alan Winstanley.

"[2] Speaking of the influence that Iggy Pop's 1977 song "The Passenger" had on "Lost Weekend", Cole recalled in 2010, "It just went that way in rehearsal and while we were aware that the rhythm part was the same, the chords and everything else was different, so we weren't bothered.

"[3] Upon its release as a single, Tom Hibbert of Smash Hits commented, "This is lovely – chiming guitars sturdily jaunting and winking at an idea based on Iggy Pop's 'The Passenger' with customary jumbly vocal delivery".

He added, "It all sounds uncharacteristically merry until one starts to pick up the words which appear to be about contracting pneumonia in Amsterdam, almost dying and then undergoing a religious conversion.
