The phrase was used on the TV recently (we were watching a cooking show) and I asked which musical it came from. So my wife and I had a disagreement. She posited “Chitty Chitty Bang Bang” and I thought of “Mary Poppins” (for some reason*). Obviously she was correct but a Google (.co.uk) search revealed this as the second highest ranking page (it does have dreadful muzak - wasn’t that a web-design idea cast beyond the Door of Night over a decade ago).
I really don’t know what to think.
*”Positively Perfect in Every Way” and all that.
