"Merrymaking at My Place" is a song by Scottish DJ Calvin Harris. The single was released on 20 August 2007 as the third single from Harris' debut studio album I Created Disco (2007). The radio edit which appears on the single has an altered chorus and several altered verses in order to remove all apparent drug references from the song.
Previous singles included "Acceptable in the 80s" and "The Girls". To promote the single, Harris asked fans through his website to host house parties. Despite some airplay and video play, the single failed to reach the UK top 40, making it to number 43 on full release. It is Harris's only song not to reach the top 40.
The music video, directed by Kinga Burza features Calvin and his friends enjoying themselves to the song, in what appears to be Calvin's grandmother's house. The location is assumed when Calvin talks to his grandmother on the telephone, just moments before his friends arrive. At the end of the video, Calvin's grandmother arrives home to find the house in a mess and has a heart attack.
