Yeah, it used to be that they'd show that American Bandstand video, and when the guy with the Gino Vannelli shirt appeared on screen, the crowd would laugh and cheer, because the guy looks so dorky. Now the Celtics have grabbed it and used it to manufacture more "game night entertainment" as they call it. The pole dancers put on Gino shirts, and do moves they copped from the video. There is a big build-up, Gino is coming! Show anyone in the crowd wearing a Gino shirt! ... turn it into a show-biz event. It's lost all its goofy appeal. Now it's just more of the same idiotic nonsense that they feel they have to feed the crowd.
As for Gino (the musician himself, not the dancer), he's from the same province that gave us Celine Dion. His biggest hits were "Living Inside Myself" and "I Just Wanna Stop". A skilled musician, but slick, highly produced, pop power-ballads aren't to everyone's taste. When he decided to go down that road, a lot of his fans lost interest.
