Sentence: Achentaler Anklöpfler in Pertisau
Austrian (Tyrolean) term

I am looking for a neat English way of describing this, if possible avoiding the word "knockers"...:)

Here is an explanation of what Anklöpfler are:
Die Anklöpfler erinnern mit ihren Besuchen an die Hirten, die auf dem Feld von der Geburt des Kindes erfahren und an Maria und Josef, die in ganz Betlehem keine Herberge finden konnten. Da die Botschaft der Hirten letztendlich eine hoffnungsvolle, freudige Nachricht ist, bringen die Anklöpfler daneben auch Humor mit in die Häuser!

„Anklöpfeln“ (dialect for “to knock”) is a practice cultivated in the Tyrolean lower Inn valley. Here, a group of mostly male singers dress up as shepherds and visit the neighbouring houses on the three Thursdays before Christmas (“knocking nights”). The singers are invited into the homes and strike up several songs to herald the Christmas message of the birth of Jesus Christ. Often, these singers are accompanied by instrumentalists. As a way of thanking the singers, they are given a minimum of one drink, some Christmas biscuits or a snack. Sometimes money is given as well, which is collected by the society of "knockers" and spent on charity.
