One of the finest comedies ever shown on English-language television, The Norman Conquests (1978; 1973 pub.) by Alan Ayckbourn, England’s most renowned comic playwright of the last forty years, is yours in part for the viewing at YouTube, in the form of Part Two of three, Living Together, in ten segments (see also the first ten minutes each of Part One, Table Manners, and Part Three, Round and Round the Garden). As a needy, shaggy hang-puppy-dog of a librarian who wants nothing more than to be loved, and nothing less than to be loved by all three of the women (his two sisters-in-law plus, oh yes, his wife) sharing with him a weekend adult-family visit at his ailing mother-in-law’s, Tom Conti is unforgettable. And Penelope Keith, Penelope Wilton, Richard Briers, Fiona Walker and David Troughton are more than a match for him. PBS stalwarts will recognize Keith and Briers (left and second) 
at once from their turns on the popular suburban sitcom Good Neighbors (UK: The Good Life), though here in The Norman Conquests they are one couple rather than members of two. Wikipedia:
Each of the plays depicts the same six characters over the same weekend in a different part of a house. Table Manners is set in the dining room, Living Together in the living room, and Round and Round the Garden in the garden. Each play is self-contained, and they may be watched in any order. Some of the scenes overlap, and on several occasions a character’s exit from one play corresponds with an entrance in another. The plays were not written to be performed simultaneously, although Ayckbourn did achieve that some twenty-five years later in House & Garden.
The 2009 Broadway revival won the Tony Award for Best Revival.
Those of us who caught the trilogy on PBS stations almost thirty years ago, and/or on VHS via our more discerning local video shops off and on ever since (thank you, Charlottesville, Virginia, c. 1990: Bliss was it in that dawn, &c.), still await, perhaps unto the digital afterlife if even then, a DVD release. Until then, enjoy one self-contained third of the whole, as shall we once more.
Thanks for these. For some reason that is a series I totally missed. Well, I was working 60 hours a week and going to college full time. I have looked for other old series as part of our movie project and dont remember seeing it either.

With a total run-time of about five hours, and shown a couple of times on PBS stations thirty years ago, with the 3-VHS box going, used, for almost $250 now (and the 2006 UK DVD about the same at c. £125 per Amazon.co.uk), you’d be a rare soul to have happened upon it at all.
