The authors of the song “Take Me Out to the Ballgame” had never seen a baseball game.
Vaudevillian Jack Norworth wrote the words in 1908 after seeing a sign on a bus advertising BASEBALL TODAY-POLO GROUNDS.
His friend Albert von Tilzer wrote the music.
It wasn’t until the song became a big sing-along hit that either of them bothered going to “root root root for the home team.”
Incidentally, while almost everybody knows the chorus, almost nobody knows the verses.
Here’s the first one to get you started:
Katie Casey was baseball mad Had the fever and had it bad.
Just to root for the hometown crew, Every sou, Katie blew,
On a Saturday her young beau Called to see if she’d like to go
To see a show but Miss Kate said, “No I’ll tell you what you can do
Take me out to the ball game”
