Carl Jularbo, better known as Calle Jularbo and born Karl Karlsson (6 June 1893, in Jularbo, Avesta Municipality, Dalarna County, Sweden – 13 February 1966, in Nacka Municipality, Stockholm County, Sweden) was the most famous Swedish accordionist of his time.
He had a very distinct personal style, that has played a significant part in forming the Swedish accordion tradition.
He was extremely productive, recording 1577 tunes and he won 158 accordion competitions.
His best known tune is Livet i Finnskogarna (roughly "Life in the Finn forests"), recorded in 1915.
This song was the basis for the Les Paul and Mary Ford hit of 1951, "Mockin' Bird Hill".
