A Very Peculiar Practice

A Very Peculiar Practice was a comedy-drama starring Peter Davison (All Creatures Great & Small, Doctor Who, At Home With The Braithwaites, Fear Stress And Anger, Distant Shores, Love For Lydia, Campion, Fiddlers Three, The Last Detective, Ain't Misbehavin'), Graham Crowden (Waiting For God, Love On A Branch Line), David Troughton (The Norman Conquests, Bonjour La Classe, Jericho, Paradise Heights, recently seen in several episodes of New Tricks), Barbara Flynn (Open All Hours, Biederbecke Trilogy, A Family At War, The Barchester Chronicles, Maigret, Cracker, Cranford), John Bird (Joint Account, El C.I.D., Absolute Power),  Lindy Whiteford (A Touch Of Frost, Getting On), Joanna Kanska (Material Girl, Sleepers), Mark Addy was in a couple episodes (The Thin Blue Line, Bonkers) and I think I saw Liz Crowther in there somewhere (Shoestring, Slinger's Day, No Place Like Home, Watching, French Fields). Hugh Grant and Kathy Burke both had one of their earliest TV appearances in this program. Nearly all the episodes begin with a rubbish truck approaching a dumpster/tip being picked over by two nuns. Got it?
