Liza Minnelli still takes regular dance classes, performs around the world and puts her star power to good use.

This weekend, the Oscar, Grammy, Tony, Emmy and Golden Globe winner (to name a few) will visit Charm City to perform for the Chimes Hall of Fame 60th Anniversary. While many of her contemporaries have put their dance shoes in moth balls, Minnelli has signed on to perform at what is arguably one of the biggest charity events of the year.
