Sadie, It's Cold Outside + Yanks Go Home

2 comedies from the 70's.

Sadie, It's Cold Outside was written by Jack Rosenthal (who in addition to writing many TV episodes, TV plays and movies, wrote The Dustbinmen, The Lovers, a series of Pardon The Expression, Moving Story) and starred Rosemary Leach (Susan's mother in My Family, Odd Socks, The Power Game, Life Begins at Forty, The Jewel in the Crown, The Charmer, Summer's Lease, Titmuss Regained, Berkeley Square, The Tomorrow People, the US sitcom Growing Pains, An Unsuitable Job for a Woman) and Bernard Hepton (The Charmer, Bleak House, Mansfield Park, Secret Army, Tinker Tailor Soldier Spy, Colditz, The Six Wives of Henry VIII).
Sadie is about a bored and discontented mid-life wife with a bored-but-contented husband. Sounds similar to Butterflies (which it pre-dates) but Sadie didn't have a Leonard to torment and her children are no longer part of her life.

Yanks Go Home took place during WWII and was about a Lancashire town and its interactions with the many American military personnel based there. With the final 6-episode series of Dad's Army in production when Yanks first aired, it seems Granada was in hopes of picking up some of the huge Dad's audience, but it didn't work out that way in the end.
With Meg Johnson (on Emmerdale for the past decade), Stuart Damon (who starred in the late 60's spy show The Champions and more recently in several American soaps), David Ross (the final episode of Last of the Summer Wine, The Green Green Grass, Roger Roger, 32 Brinkburn Street, G.B.H.), Alan MacNaughton (To Serve Them All My Days, The Sandbaggers). Peter Sallis (Last of the Summer Wine) appears in four episodes and Richard Wilson (not going to list them all) appears in two.
