As I've posted more than a few times here . . .
Victor/Victoria
I loved-loved-loved the show, but it was memorable because it was my first trip to NYC, and walking through Times Square the first time was magical. (Now, after so many trips, I'm jaded and usually avoid the main streets so I can easily get to my destination LOL) I had just arrived at the airport (Newark) that morning, and my buddy who grew up in Manhattan and went to Julliard was my guide. He scored great seats, 10th row center. Seeing Julie Andrews so close was a memorable experience, as was a then unknown (to me) Rachel York, who through a friend I've since had the pleasure of meeting a few times after shows and just adore her. The music, the sets (I still vividly see the streets give way to Chez Louis, Toddy's flat, and the hotel) and the laugh-out-loud book, lyrics, and movements.
I have a lot of "best" shows but V/V is always on a level separate from the others for these reasons.
