Back in April 1969, there was a special Spring Training game at Yankee Stadium. It was between the Yankees and Giants. As a teenager, I was a big Yankee fan and wouldn't miss this for anything.
I cut out of school that day to attend the game. I brought my Super 8 movie camera along with me to film parts of the game. Here is one scene of the Say Hey Kid himself.
