David Hyde Pierce, Karen Ziemba and Debra Monk were all so kind and gracious (it was pooring rain!).
Also Norm Lewis was so humbled when I mentioned to him that I fell in love with voice when he sang "You Should be Loved" in Side Show after The Little Mermaid.
One of the coolest was Jaqueline Piro-Donovan who chatted me up for about 20 minutes after Witches of Eastwick.
But to me hands down the nicest EVER... has been Linda Eder. She is so into her audience when she comes out and stays no matter how long they chat her up. The first time I ever saw her it was raining and her Limo had not shown up and instead of going back inside she stood out with the 5 of us who waited and talked about everything from her concert to the best food around the country. She was so fab!
"Whenever I get gloomy with the state of the world, I think about the arrivals gate at Heathrow Airport. General opinion's starting to make out that we live in a world of hatred and greed, but I don't see that. It seems to me that love is everywhere. Often it's not particularly dignified or newsworthy, but it's always there - fathers and sons, mothers and daughters, husbands and wives, boyfriends, girlfriends, old friends. When the planes hit the Twin Towers, as far as I know none of the phone calls from the people on board were messages of hate or revenge - they were all messages of love. If you look for it, I've got a sneaky feeling you'll find that love actually is all around."
