Krymplings
Krymplings (a pun on Grymlings) was a Swedish supergroup punk band consisting of five lead singers in Swedish punk music which existed in 1994.
The band was Ulke ( Strebers, Dia Psalma), Mart Hällgren ( De Lyckliga Kompisarna), Per Granberg ( Charta 77), Curre Sandgren ( Coca Carola) and Mongo ( Köttgrottorna). Everyone wrote the songs, and everyone sang, except for the one who wrote the song, who was not allowed to sing.
Krymplings made a record and a tour (called Dunken tur -94), and then stopped playing. However they made a slight comeback in the summer of 2004 for one concert at the Swedish music festival Augustibuller, and one concert at Kafé 44 in Stockholm. Since that, nothing more has happened.
