Whilst doing a bit of research on the origins and customs of Hallowe’en recently, I came across a Youtube video of a Hallowe’en song in French which I used to do with my classes when I taught in an international school some 15 + years ago. It covers most of the vocabulary to do with Hallowe’en and the tune is very catchy. The pupils loved it!
If you are looking for a song in German you could try teaching “Süßes oder Saures” (Trick or treat) – the lyrics can be found on a downloable .pdf Kindergarten 1 – Feste feiern.
