"Happy Ending" is the 5th single release from London-based singer Mika. Taken from his debut album Life in Cartoon Motion, producer Greg Wells remixed and rearranged the single, released online on 8 October 2007, and in shops on CD and 7" vinyl on 15 October 2007. The single charted as Mika's fourth straight UK Top 10 single out of his first four, continuing his UK success so far, peaking at #7 in the UK Singles Chart. It was the fifth most added song to Australian radio in late October 2007 and was released there officially on 12 November 2007, as the 3rd single despite digital track sales placing the song in the ARIA singles chart before the official release.
