1970/80s Chocolate pudding with sponge fingers & bananas

[Nels22]

Does anyone have the recipe that my mum used to make in the late 1970s early 80s that consisted of a chocolate blancmange/pudding with sliced bananas served in a jelly mould with orange juice soaked sponge fingers around the edge and at the bottom of the pudding.

Mum sadly now has Alzheimer’s so can no longer remember but I would love to make it for her. I suspect the recipe was on the back of the blancmange/sponge fingers packet. I checked the most popular cookbook of the era The Dairy Book of Home Cookery but no luck there.

Any suggestions would be greatly appreciated.

A couple of similar sounding possibilities I remember from my 80's childhood...

Sherry Trifle - my parents used to make that with sponge fingers... And, although mine never did, I think some people used to substitute sherry for their fruit juice of choice.

That might account for the orange, but doesn't involve chocolate (unless it was a chocolate trifle).

And my Dad sometimes made a similar pudding which did have chocolate & sponge fingers (I don't remember orange juice being involved, but can't swear it wasn't)...

In our house, it was called "Tombstone Pudding" - I'm not sure if that's what it was commonly known as or if that was just a "family name" for it!

I did just have a quick Google for that, but all it brought up was "gravestone pudding" which, I guess, could be a modern interpretation of it.

Also while Googling for it, I found this link which has a few more possible suggestions:
