They are called Patrask wich means ragtag or rabble. It is a group that tour medieval market festivals all over sweden and some of the nordic countrys to give that authentic sound to the festivitis.
For fun they sometimes do medlys with well known modern songs in medieval style.
This particular clip is from a area in the swedish town Örebro called Wadköping, it is an area with very old buildings still standing.
Naturaly it is a perfect place for medieval reinactments, festivals and markets.
