Wow... AngelStar, that is an amazing find Very creative

Simpler... The only other thing which comes to mind is "15 minutes of fame" - but that is Mr. Warholl and not Hitchcock. Or well, we could make it completely simple and call the "discovery" of Ms Boyle an historic event

I wonder which of the clues I identified
Maybe the song... in that case, the asking for the name might be the event where Doris Mary Anne von Kappelhoff changed her name to Doris Day
Ow wait! What about
D-Day (June 6, 1944)
If that's the case, it's really a marvelous way to portray it
