What Broadway show is this tune from?

I’m searching for info about a certain song & bewildered that it’s so hard to find. I know that it was written by Jerry Herman & I believe it’s titled “Show Tune in 2/4”. The lyrics, at least in part, go like this:
“There is no tune as exciting
As a show tune in 2/4
When it’s played, you can just tell
There’s footlights everywhere.
When it’s played, you can just smell
The greasepaint in the air.”
Almost anyone who has heard this will remember it but I can’t find anything about this song online BECAUSE I DON’T KNOW WHICH PLAY it is from.
I’ve tried looking on Google, [the ibdb.com website is currently down(internet Broadway database)], the American Theatre Wing website & PlaybillVault.com all to no avail.

What show, additional lyrics, sheet music, the year it was written… nothing.

Any input would be appreciated & thanks!
