Grease is the Word

So I received a last minute phone call from my future Aunt-in-law who had an extra ticket for Grease for tonight at Shea's. Now I'm sure this will come as no surprise-but Grease is my all time favorite movie (I literally know every line, and for that, no one will ever watch it with me!). So naturally...I said yes! It was great-so much fun, fantastic vocals, superb accompaniment, and of course-lots of leather jackets! For those familiar with the show (movie or Broadway version) you know the scene where Frenchie meets her guardian angel (in the movie it was Frankie Avalon) and he tells her to "go back to high school." The man who played her guardian angel was none other than....Taylor Hicks. That is right ladies and gentleman...Taylor Hicks. He was hiding in an ice cream cone (the scene was sit in a soda shop) that was hanging.....and as the music began, there he was...and it was quite a scene. He was definitely trying to dance like Elvis (though how does one do that when in an ice cream cone?!)-but couldn't pull it off. Anyways-that was the only scene he was in. At the end of the show, when they have everyone come out and the audience applauds...you assume the show is completed. But shortly after-there was an announcement that Taylor was going to be performing his latest hit single for us all! And all I could think was...wow, promoting his music at the end of Grease? I was wondering if anyone has even been to a musical in which one of the cast members was a star...and they performed at the end. I would be curious to hear your thoughts!
