I believe so, but not the incident that I was referring to. However, I will accept that answer because it fits the requirements of my question. The answer I was looking for came from the latest Hallowed Ground journal from the Civil War Trust. This issue is dedicated to Gettysburg.
The brief information that I saw was that 15-year-old George Gitt hid under the platform where Lincoln gave the Gettsyburg Address so that he could hear "from the feet of my hero."
