Name of the old thriller

Hi everyone, I’m trying to identify an English-language TV movie I watched on TV in the early 1990s, but I think the film itself might have been made in the 1970s or 1980s. Here’s what I remember: The husband is abusive, possibly beats his wife. He works in (or owns) a construction company. At one point, he tries to kill his wife by throwing her into a deep pit and pouring concrete over it (burying her alive). She manages to survive, I think by singing while trapped, and someone hears her. There is a family moment where the mother and children sing “Yellow Submarine” in the car. In the end, the wife survives. It was definitely in English. I already checked Buried Alive (1990), but that doesn’t fully match the details (no concrete and no singing scene). Does anyone know the title of this movie? Thanks in advance!
