This is possibly and English film. I believe it is from the 60s or 70s. I believe it is about a coven of witches. It envolves a couple ( she is brunette I believe, and the husband is sandy blonde). I recall that the wife ends up joining the coven and the husband at the very end gets his tongue cut out ( he lives). The last seen is him sitting in a rocking chair looking out a bay window. It isn’t Burnt Offerings.
