Co-incidence.... Chicken Maryland..... taught my kids how to cook it this weekend from 1989 Sunday Times amazing coffee table cook book. Also their corn fritters, was v cheap and posh KFC alternative but I don't remember my mum ever cooking it in the 1970's
Fondue is for a fondue party, ditto raclette. Had a meat fondue in Bruges last year and was great fun for sharing but not Abigail's Party posh.
1970's would def be good choices with steak or coq au vin or duck a l'orange.
Crepes Suzette possibly for a show off ending?
That and Black Forest roulade will polish them off.
Very definitely you must have butter curls, get a funny wibbly edged spoon thing, drag across slightly soft butter then put the curls in a dish in the fridge to go rock hard.
You serve them with warm rolls that are put on the table in a sort of bizarre multi pocketed fabric daisy flower thing.
You also need napkin rings, a silver plated candelabra and decanters for everything.
Start the meal with sherry, though for true authenticity you should have decanted it for Christmas and left the remainders on the drinks trolley since.
I can do a full list of all drinks regularly drunk at which points of the evening, very bizarre combinations, would prob be better off with a fish bowl and some straws.
(disclaimer was at primary school at end of 70's and used to nick butter curls out of the fridge.)
