"Hello Hazel" from HAZEL FLAGG. Someone needs to bring that show back!
Also "Love Can't Happen" from GRAND HOTEL. Ditto on bringing that one back.
Re THE APPLE TREE the song "Who Is She?" is much more about being starstruck IMO.
One could argue "Hello, Dolly!" is kindof about that, or "If They Could See Me Now."
"Honestly Sincere" from BYE BYE BIRDIE isn't in terms of text, but contextually thats the idea.
There's a song from FADE OUT - FADE IN that has a theme like that but I cannot remember it.
