Where are you getting the word ‘toddlin’ from? I fail to see that in the article linked.

Here is what Wikipedia had to say:
"Chicago" is a popular song written by Fred Fisher and published in 1922. The original sheet music variously spelled the title "Todd'ling" or "Toddling." The song has been recorded by many artists, but the best-known versions are by Frank Sinatra, Ben Selvin and Judy Garland.
It’s NOT in the article. it was a joke. Chicago is known as the ‘Toddlin Town’ and the meaning of that word is not really known so a joke.
Sheesh!
Oh yes, by the Chairman of the board.
