"Kung för en dag" or "Kung i baren" is the second track of Magnus Uggla's 1997 album Karaoke. It was written by Magnus Uggla together with Anders Henriksson. Lyrically dealing with partying when the wage arrives for the month, the song was the album's major hit. The music video shows Olle Sarri acting as partying. On 1 July 2008, when Uggla appeared as guest, the song was performed as a sing-along song at Allsång på Skansen on 1 July 2008. On 7 July 2009, when Uggla appeared together with Rolandz, the song was once again performed as a sing-along song.
