There’s a few different boss from the 1950s-70s that could be. That sounds like a weird description of the Great Rite, with the weird parts being that a) there is no requirement for it to be am old man and a young woman and b) there is no requirement for the man to lead the rite – usually it’s mutual or, as you supposed, led by the woman.
From what I’ve seen and heard, the Great Rites is talked about a lot more than it is practised. When it is practised, it’s much more likely to be just the two participants – you don’t need a circle of coven members for it.
