Doesn’t work for me. I can’t hear it without flashing to “Annie Hall.”
“'La-dee-da' was fading out of use in the language until it staged something of a comeback following its use by the eponymous heroine of the 1977 film Annie Hall.
Diane Keaton's character actually said 'La-dee-da, la-dee-da, la la'. This wasn't a reference to swanky or snobbish behavior - it was used as a meaningless phrase, spoken out of context when nervous, to emphasize Hall's ditzy personality.”
