It was anything but a typical day as Toby Keith visited troops as part of his ninth USO Tour. 

As he was about to take the stage late last week, the base in Iraq where he was performing came under mortar attack.

He tweeted back some pictures and commentary — and yes, went on with the show.

He tweets that four mortars hit nearby as he was about to perform and they had to wait in bunkers until they got the "all clear" signal.
