Norworth, who also wrote "Shine On Harvest Moon", is quoted in "Three Men on Third" (Carl Sifakis; New York: Prentice Hall, 1994) regarding his long absence from the park. He said, "So what? Harry Williams wrote 'In the Shade of the Old Apple Tree' and I am sure he never saw a blade of grass. If he ever got three blocks off 26th Street in Manhattan, it was a great occasion."
His composer was Albert Von Tilzer, who himself never saw a major league game until 1928.
The song is now in the public domain, and was featured in several versions on the soundtrack of the mini-series "Baseball: A Film by Ken Burns", including a superb rendition by Carly Simon.
Katie Casey saw all the games
Knew the players by their first names
Told the umpire he was wrong
All along, good and strong
When the score was just two to two
Katie Casey knew what to do
Just to cheer up the boys she knew
She made the gang sing this song
