The April 2, 2011 edition of THE WASHINGTON POST reported that "Soul singer Gladys Knight plans to be at Union Station on May 7 to host Amtrak's fourth annual National Train Day festivities." "The exhibits in the District will feature a train commemorating Amtrak's 40th Anniversary" and a recognition of the B&O Railroad.
Personally, I wonder what time she will sing "Midnight Train to Georgia"? I don't want to miss that!
