Allan Olsen (born in Grønholt, Vendsyssel on March 18, 1956) is a Danish folkrock musician and singer-songwriter. His famous live performances combine his songs with satirical and dryly tempered anecdotes; the music delivered either acoustically or with a rock band. In the period 1983 to 1992, he was part of Dalton, a supergroup trio made of Olsen, Lars Lilholt and Johnny Madsen.
