"Singin' In the Rain"....the ORIGINAL Jukebox musical!
There will be NO mocking of "Singin' in the Rain" in my presence, thankyewverymuch... it was the first stage show I ever saw, and my siblings and I spent the next weeks bantering back and forth in our best nasal voices: "and I can't stand him!" "caaahhnt!" "caaaant!")
That being said, I'd probably mock the show if I saw it today... *sigh* to paraphrase Terry Pratchett: It's not that I wish that I knew then what I know now; I wish that I didn't know now what I didn't know then...
